E Ericsson Internal PRODUCT SPECIFICATION Prepared (also subject responsible if other) SEC/S Gavin Du Approved Checked BMR 463 series POL Regulators Input 4.5-14 V, Output up to 25 A / 82.5 W Safety Specification General information Ericsson Power Modules DC/DC converters and DC/DC regulators are designed in accordance with safety standards IEC/EN/UL 60950-1 Safety of Information Technology Equipment. IEC/EN/UL 60950-1 contains requirements to prevent injury or damage due to the following hazards: * * * * * * 3 (4) No. Electrical shock Energy hazards Fire Mechanical and heat hazards Radiation hazards Chemical hazards On-board DC/DC converters and DC/DC regulators are defined as component power supplies. As components they cannot fully comply with the provisions of any safety requirements without "Conditions of Acceptability". Clearance between conductors and between conductive parts of the component power supply and conductors on the board in the final product must meet the applicable safety requirements. Certain conditions of acceptability apply for component power supplies with limited stand-off (see Mechanical Information for further information). It is the responsibility of the installer to ensure that the final product housing these components complies with the requirements of all applicable safety standards and regulations for the final product. Component power supplies for general use should comply with the requirements in IEC 60950-1, EN 60950-1 and UL 60950-1 Safety of Information Technology Equipment. There are other more product related standards, e.g. IEEE 802.3 CSMA/CD (Ethernet) Access Method, and ETS-300132-2 Power supply interface at the input to telecommunications equipment, operated by direct current (dc), but all of these standards are based on IEC/EN/UL 60950-1 with regards to safety. Ericsson Power Modules DC/DC converters and DC/DC regulators are UL 60950-1 recognized and certified in accordance with EN 60950-1. The flammability rating for all construction parts of the products meet requirements for V-0 class material according to IEC 60695-11-10, Fire hazard testing, test flames - 50 W horizontal and vertical flame test methods. The products should be installed in the end-use equipment, in accordance with the requirements of the ultimate application. Normally the output of the DC/DC converter is considered as SELV (Safety Extra Low Voltage) and the input source must be isolated by minimum Double or Reinforced Insulation from the primary circuit (AC mains) in accordance with IEC/EN/UL 60950-1. 1/1301-BMR 463Technical Uen Date 2014-01-03 Specification Rev Reference F X 3 EN/LZT 146 434 R4B February 2014 (c) Ericsson AB Isolated DC/DC converters It is recommended that a slow blow fuse is to be used at the input of each DC/DC converter. If an input filter is used in the circuit the fuse should be placed in front of the input filter. In the rare event of a component problem that imposes a short circuit on the input source, this fuse will provide the following functions: * * Isolate the fault from the input power source so as not to affect the operation of other parts of the system. Protect the distribution wiring from excessive current and power loss thus preventing hazardous overheating. The galvanic isolation is verified in an electric strength test. The test voltage (Viso) between input and output is 1500 Vdc or 2250 Vdc (refer to product specification). 24 V DC systems The input voltage to the DC/DC converter is SELV (Safety Extra Low Voltage) and the output remains SELV under normal and abnormal operating conditions. 48 and 60 V DC systems If the input voltage to the DC/DC converter is 75 Vdc or less, then the output remains SELV (Safety Extra Low Voltage) under normal and abnormal operating conditions. Single fault testing in the input power supply circuit should be performed with the DC/DC converter connected to demonstrate that the input voltage does not exceed 75 Vdc. If the input power source circuit is a DC power system, the source may be treated as a TNV-2 circuit and testing has demonstrated compliance with SELV limits in accordance with IEC/EN/UL60950-1. Non-isolated DC/DC regulators The input voltage to the DC/DC regulator is SELV (Safety Extra Low Voltage) and the output remains SELV under normal and abnormal operating conditions.

Absolute Maximum Ratings, sometimes referred to as no destruction limits, are normally tested with one parameter at a time exceeding the limits in the Electrical Specification. If exposed to stress above these limits, function and performance may degrade in an unspecified manner. Configuration File This product is designed with a digital control circuit. The control circuit uses a configuration file which determines the functionality and performance of the product. The Electrical Specification table shows parameter values of functionality and performance with the default configuration file, unless otherwise specified. The default configuration file is designed to fit most application needs with focus on high efficiency. If different characteristics are required it is possible to change the configuration file to optimize certain performance characteristics. Note that current sharing operation requires changed configuration file. See application notes AN307 and AN312 for further information. In this Technical specification examples are included to show the possibilities with digital control. See Operating Information section for information about tradeoffs when optimizing certain key performance characteristics.

A ground layer will increase the stray capacitance in the PWB and improve the high frequency EMC performance. Power Management Overview This product is equipped with a PMBus interface. The product incorporates a wide range of readable and configurable power management features that are simple to implement with a minimum of external components. Additionally, the product includes protection features that continuously safeguard the load from damage due to unexpected system faults. A fault is also shown as an alert on the SALERT pin. The following product parameters can continuously be monitored by a host: Input voltage, output voltage/current, and internal temperature. If the monitoring is not needed it can be disabled and the product enters a low power mode reducing the power consumption. The protection features are not affected. The product is delivered with a default configuration suitable for a wide range operation in terms of input voltage, output voltage, and load. The configuration is stored in an internal Non-Volatile Memory (NVM). All power management functions can be reconfigured using the PMBus interface. Please contact your local Ericsson Power Modules representative for design support of custom configurations or appropriate SW tools for design and download of your own configurations. Input Voltage The input voltage range, 4.5 - 14 V, makes the product easy to use in intermediate bus applications when powered by a non-regulated bus converter or a regulated bus converter. See Ordering Information for input voltage range. Ericsson Internal PRODUCT SPECIFICATION E Prepared (also subject responsible if other) EAB/FJB/GMF EHOSMIR Approved 2 (18) No. 30/1301-BMR 463 Uen Checked BMR 463 series POL Regulators (EKRIROB) EAB/FJB/GMF (Ksenia Harrisen) Input 4.5-14 V, Output up to 25 A / 82.5 W TechnicalReference Specification Date Rev 2014-02-11 EN/LZT 146 434 R4B February 2014 D 42 (c) Ericsson AB Input Under Voltage Lockout, UVLO The product monitors the input voltage and will turn-on and turn-off at configured levels. The default turn-on input voltage level setting is 4.20 V, whereas the corresponding turn-off input voltage level is 3.85 V. Hence, the default hysteresis between turn-on and turn-off input voltage is 0.35 V. Once an input turnoff condition occurs, the device can respond in a number of ways as follows: significant inductance, the addition a capacitor with low ESR at the input of the product will ensure stable operation. 1. Continue operating without interruption. The unit will continue to operate as long as the input voltage can be supported. If the input voltage continues to fall, there will come a point where the unit will cease to operate. where I load is the output load current and D is the duty cycle. 2. Continue operating for a given delay period, followed by shutdown if the fault still exists. The device will remain in shutdown until instructed to restart. 3. Initiate an immediate shutdown until the fault has been cleared. The user can select a specific number of retry attempts. The default response from a turn-off is an immediate shutdown of the device. The device will continuously check for the presence of the fault condition. If the fault condition is no longer present, the product will be re-enabled. The turn-on and turn-off levels and response can be reconfigured using the PMBus interface. Remote Control Vext CTRL GND The product is equipped with a remote control function, i.e., the CTRL pin. The remote control can be connected to either the primary negative input connection (GND) or an external voltage (Vext), which is a 3 - 5 V positive supply voltage in accordance to the SMBus Specification version 2.0. The CTRL function allows the product to be turned on/off by an external device like a semiconductor or mechanical switch. By default the product will turn on when the CTRL pin is left open and turn off when the CTRL pin is applied to GND. The CTRL pin has an internal pull-up resistor. When the CTRL pin is left open, the voltage generated on the CTRL pin is max 5.5 V. If the device is to be synchronized to an external clock source, the clock frequency must be stable prior to asserting the CTRL pin. The product can also be configured using the PMBus interface to be "Always on", or turn on/off can be performed with PMBus commands. Input and Output Impedance The impedance of both the input source and the load will interact with the impedance of the product. It is important that the input source has low characteristic impedance. The performance in some applications can be enhanced by addition of external capacitance as described under External Decoupling Capacitors. If the input voltage source contains External Capacitors Input capacitors: The input ripple RMS current in a buck converter is equal to Eq. 1. I inputRMS I load D 1 D , The maximum load ripple current becomes I load 2 . The ripple current is divided into three parts, i.e., currents in the input source, external input capacitor, and internal input capacitor. How the current is divided depends on the impedance of the input source, ESR and capacitance values in the capacitors. A minimum capacitance of 300 F with low ESR is recommended. The ripple current rating of the capacitors must follow Eq. 1. For high-performance/transient applications or wherever the input source performance is degraded, additional low ESR ceramic type capacitors at the input is recommended. The additional input low ESR capacitance above the minimum level insures an optimized performance. Output capacitors: When powering loads with significant dynamic current requirements, the voltage regulation at the point of load can be improved by addition of decoupling capacitors at the load. The most effective technique is to locate low ESR ceramic and electrolytic capacitors as close to the load as possible, using several capacitors in parallel to lower the effective ESR. The ceramic capacitors will handle high-frequency dynamic load changes while the electrolytic capacitors are used to handle low frequency dynamic load changes. Ceramic capacitors will also reduce high frequency noise at the load. It is equally important to use low resistance and low inductance PWB layouts and cabling. External decoupling capacitors are a part of the control loop of the product and may affect the stability margins. Stable operation is guaranteed for the following total capacitance CO in the output decoupling capacitor bank where Eq. 2. CO Cmin , Cmax 300, 15000 F. The decoupling capacitor bank should consist of capacitors which has a capacitance value larger than C C min and has an ESR range of Eq. 3. ESR ESRmin , ESRmax 5, 30 m The control loop stability margins are limited by the minimum time constant min of the capacitors. Hence, the time constant of the capacitors should follow Eq. 4. Eq. 4. min Cmin ESRmin 1.5 s This relation can be used if your preferred capacitors have parameters outside the above stated ranges in Eq. 2 and Eq.3.

C C min ESR For a total capacitance outside the above stated range or capacitors that do not follow the stated above requirements above a re-design of the control loop parameters will be necessary for robust dynamic operation and stability. See technical paper TP022 for further information. Control Loop The product uses a voltage-mode synchronous buck controller with a fixed frequency PWM scheme. Although the product uses a digital control loop, it operates much like a traditional analog PWM controller. As in the analog controller case, the control loop compares the output voltage to the desired voltage reference and compensation is added to keep the loop stable and fast. The resulting error signal is used to drive the PWM logic. Instead of using external resistors and capacitors required with traditional analog control loops, the product uses a digital Proportional-Integral-Derivative (PID) compensator in the control loop. The characteristics of the control loop is configured by setting PID compensation parameters. These PID settings can be reconfigured using the PMBus interface. Control Loop Compensation Setting The products without DLC are by default configured with a robust control loop compensation setting (PID setting) which allows for a wide range operation of input and output voltages and capacitive loads as defined in the section External Decoupling Capacitors. For an application with a specific input voltage, output voltage, and capacitive load, the control loop can be optimized for a robust and stable operation and with an improved load transient response. This optimization will minimize the amount of required output decoupling capacitors for a given load transient requirement yielding an optimized cost and minimized board space. Dynamic Loop Compensation (DLC) Only some of the products that this specification covers have this feature (see section Ordering Information). The DLC feature might in some documents be referred to as "Auto Compensation" or "Auto Tuning" feature. The DLC feature measures the characteristics of the power train and calculates the proper compensator PID coefficients. The default configuration is that once the output voltage ramp up has completed, the DLC algorithm will begin and a new optimized compensator solution (PID setting) will be found and TechnicalReference Specification Date Rev 2014-02-11 EN/LZT 146 434 R4B February 2014 D 43 (c) Ericsson AB implemented. The DLC algorithm typically takes between 50 ms and 200 ms to complete. By the PMBus command AUTO_COMP_CONFIG the user may select between several different modes of operation: Disable Autocomp once, will run DLC algorithm each time the output is enabled (default configuration) Autocomp every second will initiate a new DLC algorithm each 1 second Autocomp every minute will initiate a new DLC algorithm every minute. The DLC can also be configured to run once only after the first ramp up (after input power have been applied) and to use that temporary stored PID settings in all subsequent ramps. If input power is cycled a new DLC algorithm will be performed after the first ramp up. The default setting is however to run the DLC algorithm after every ramp up. The DLC algorithm can also be initiated manually by sending the AUTO_COMP_CONTROL command. The DLC can also be configured with Auto Comp Gain Control. This scales the DLC results to allow a trade-off between transient response and steady-state duty cycle jitter. A setting of 100% will provide the fastest transient response while a setting of 10% will produce the lowest jitter. The default is 50%. Changing DLC and PID Setting Some caution must be considered while DLC is enabled and when it is changed from enabled or disabled. When operating, the controller IC uses the settings loaded in its (volatile) RAM memory. When the input power is applied the RAM settings are retrieved from the pin-strap resistors and the two non-volatile memories (DEFAULT and USER). The sequence is described in the "Initialization Procedure" section. When DLC is enabled: When DLC is enabled, the normal sequence (after input power has been applied) that a value stored in the user non-volatile memory overwrites any previously loaded value does not apply for the PID setting (stored in the PID_TAPS register). The PID setting in the user non-volatile memory is ignored and a nonconfigurable default PID setting is loaded to RAM to act as a safe starting value for the DLC. Once the output has been enabled and the DLC algorithm has found a new optimized PID setting it will be loaded in RAM and used by the control loop. When saving changes to the user non-volatile memory, all changes made to the content of RAM will be saved. This also includes the default PID setting (loaded to RAM to act as a safe starting value) or the PID setting changed by the DLC algorithm after enabling output. The result is that as long as DLC is enabled the PID setting in the user non-volatile memory is ignored, but it might accidentally get overwritten. When changing DLC from disabled to enabled: A non-configurable default PID setting is loaded to RAM to act as a safe starting value for the DLC (same as above). Ericsson Internal PRODUCT SPECIFICATION E Prepared (also subject responsible if other) EAB/FJB/GMF EHOSMIR Approved 4 (18) No. 30/1301-BMR 463 Uen Checked BMR 463 series POL Regulators (EKRIROB) EAB/FJB/GMF (Ksenia Harrisen) Input 4.5-14 V, Output up to 25 A / 82.5 W When changing DLC from enabled to disabled: When changing DLC from enabled to disabled, the PID setting in the user non-volatile memory will be loaded to RAM. Any new optimized PID setting in RAM will be lost, if not first stored to the user non-volatile memory. When DLC is disabled: When DLC is disabled and input power has been applied, the PID setting in the user non-volatile memory will be loaded to RAM and used in the control loop. The original PID setting in the user non-volatile memory is quite slow and not recommended for optimal performance. If DLC is disabled it is recommended to either: 1. Use the DLC to find optimized PID setting. 2. Use Loop Compensator Tool in Ericsson Power Designer to find appropriate PID setting. 3. Use Universal PID as defined below. The Universal PID setting (taps) is: A = 4580.75, B = -8544.00, C = 3972.81 Write 0x7CF84DFE85807D8F26 to PID_TAPS register and write command STORE_USER_ALL Note that if DLC is enabled, for best results VI must be stable before DLC algorithm begins. Load Transient Response Optimization The product incorporates a Non-Linear transient Response, NLR, loop that decreases the response time and the output voltage deviation during a load transient. The NLR results in a higher equivalent loop bandwidth than is possible using a traditional linear control loop. The product is pre-configured with appropriate NLR settings for robust and stable operation for a wide range of input voltage and a capacitive load range as defined in the section External Decoupling Capacitors. For an application with a specific input voltage, output voltage, and capacitive load, the NLR configuration can be optimized for a robust and stable operation and with an improved load transient response. This will also reduce the amount of output decoupling capacitors and yield a reduced cost. However, the NLR slightly reduces the efficiency. In order to obtain maximal energy efficiency the load transient requirement has to be met by the standard control loop compensation and the decoupling capacitors. The NLR settings can be reconfigured using the PMBus interface. See application note AN306 for further information. Remote Sense The product has remote sense that can be used to compensate for voltage drops between the output and the point of load. The sense traces should be located close to the PWB ground layer to reduce noise susceptibility. Due to derating of internal output capacitance the voltage drop should be kept below VDROPMAX (5.5 VO ) / 2 . A large voltage drop will impact the electrical performance of the regulator. If the TechnicalReference Specification Date Rev 2014-02-11 EN/LZT 146 434 R4B February 2014 D 44 (c) Ericsson AB remote sense is not needed, +S should be connected to VOUT and -S should be connected to GND. Output Voltage Adjust using Pin-strap Resistor Using an external Pin-strap resistor, RSET, the output voltage can be set in the VSET range 0.6 V to 3.3 V at 28 RSET different levels shown in the PREF table below. The resistor should be applied between the VSET pin and the PREF pin. RSET also sets the maximum output voltage, see section "Output Voltage Range Limitation". The resistor is sensed only during product start-up. Changing the resistor value during normal operation will not change the output voltage. The input voltage must be at least 1 V larger than the output voltage in order to deliver the correct output voltage. See Ordering Information for output voltage range. The following table shows recommended resistor values for RSET. Maximum 1% tolerance resistors are required. VO [V] RSET[k] VO [V] RSET[k] 0.60 10 1.50 46.4 0.65 11 1.60 51.1 0.70 12.1 1.70 56.2 0.75 13.3 1.80 61.9 0.80 14.7 1.90 68.1 0.85 16.2 2.00 75 0.90 17.8 2.10 82.5 0.95 19.6 2.20 90.9 1.00 21.5 2.30 100 1.05 23.7 2.50 110 1.10 26.1 3.00 121 1.15 28.7 3.30 133 1.20 31.6 1.25 34.8 1.30 38.3 1.40 42.2 The output voltage and the maximum output voltage can be pin strapped to three fixed values by connecting the VSET pin according to the table below. VO [V] VSET 0.60 Shorted to PREF 1.2 Open "high impedance" 2.5 Logic High, GND as reference Ericsson Internal PRODUCT SPECIFICATION E Prepared (also subject responsible if other) EAB/FJB/GMF EHOSMIR 30/1301-BMR 463 Uen Approved Checked BMR 463 series POL Regulators (EKRIROB) EAB/FJB/GMF (Ksenia Harrisen) Input 4.5-14 V, Output up to 25 A / 82.5 W Output Voltage Adjust using PMBus The output voltage set by pin-strap can be overridden by configuration file or by using a PMBus command. See Electrical Specification for adjustment range. When setting the output voltage by configuration file or by a PMBus command, the specified output voltage accuracy is valid only when the set output voltage level falls within the same bin range as the voltage level defined by the pin-strap resistor RSET. The applicable bin ranges are defined in the table below. Valid accuracy for voltage levels outside the applicable bin range is two times the specified. Example: Nominal VO is set to 1.10 V by RSET = 26.1 k. 1.10 V falls within the bin range 0.988-1.383 V, thus specified accuracy is valid when adjusting VO within 0.988-1.383V. VO bin ranges [V] 0.600 - 0.988 0.988 - 1.383 1.383 - 1.975 TechnicalReference Specification Date Rev 2014-02-11 EN/LZT 146 434 R4B February 2014 D 45 (c) Ericsson AB Over Voltage Protection (OVP) The product includes over voltage limiting circuitry for protection of the load. The default OVP limit is 15% above the nominal output voltage. If the output voltage exceeds the OVP limit, the product can respond in different ways: 1. Initiate an immediate shutdown until the fault has been cleared. The user can select a specific number of retry attempts. 2. Turn off the high-side MOSFET and turn on the low-side MOSFET. The low-side MOSFET remains ON until the device attempts a restart, i.e. the output voltage is pulled to ground level (crowbar function). The default response from an overvoltage fault is to immediately shut down as in 2. The device will continuously check for the presence of the fault condition, and when the fault condition no longer exists the device will be re-enabled. For continuous OVP when operating from an external clock for synchronization, the only allowed response is an immediate shutdown. The OVP limit and fault response can be reconfigured using the PMBus interface. Under Voltage Protection (UVP) The product includes output under voltage limiting circuitry for protection of the load. The default UVP limit is 15% below the nominal output voltage. The UVP limit can be reconfigured using the PMBus interface. 1.975 - 2.398 2.398 - 2.963 2.963 - 3.753 Output Voltage Range Limitation The output voltage range that is possible to set by configuration or by the PMBus interface is limited by the pinstrap resistor RSET. The maximum output voltage is set to 110% of the nominal output value defined by RSET, VO , MAX 1.1 VO , RSET . This protects the load from an over voltage due to an accidental wrong PMBus command. Output Voltage Adjust Limitation using PMBus In addition to the maximum output voltage limitation by the pinstrap resistor RSET, there is also a limitation in how much the output voltage can be increased while the output is enabled. If output is disabled then RSET resistor is the only limitation. Example: If the output is enabled with output voltage set to 1.0 V, then it is only possible to adjust/change the output voltage up to 1.7V as long as the output is enabled. VO setting when enabled [V] 5 (18) No. VO set range while enabled [V] 0.000 - 0.988 ~0.2 to >1.2 0.988 - 1.383 ~0.2 to >1.7 1.383 - 1.975 ~0.2 to >2.5 1.975 - 2.398 ~0.2 to >2.97 2.398 - 2.963 ~0.2 to >3.68 2.963 - 3.753 ~0.2 to >4.65 Power Good The product provides a Power Good (PG) flag in the Status Word register that indicates the output voltage is within a specified tolerance of its target level and no fault condition exists. If specified in section Connections, the product also provides a PG signal output. The PG pin is active high and by default open-drain but may also be configured as push-pull via the PMBus interface. By default, the PG signal will be asserted when the output reaches above 90% of the nominal voltage, and de-asserted when the output falls below 85% of the nominal voltage. These limits may be changed via the PMBus interface. A PG delay period is defined as the time from when all conditions within the product for asserting PG are met to when the PG signal is actually asserted. The default PG delay is set to 10 ms. This value can be reconfigured using the PMBus interface. For products with DLC the PG signal is by default asserted directly after the DLC operation have been completed. If DLC is disabled the configured PG delay will be used. This can be reconfigured using the PMBus interface. Switching Frequency The fundamental switching frequency is 320 kHz, which yields optimal power efficiency. The switching frequency can be set to any value between 200 kHz and 640 kHz using the PMBus interface. The switching frequency will change the efficiency/power dissipation, load transient response and output ripple. For optimal control loop performance the control loop must be re-designed when changing the switching frequency. Ericsson Internal PRODUCT SPECIFICATION E Prepared (also subject responsible if other) EAB/FJB/GMF EHOSMIR Approved 6 (18) No. 30/1301-BMR 463 Uen Checked BMR 463 series POL Regulators (EKRIROB) EAB/FJB/GMF (Ksenia Harrisen) Input 4.5-14 V, Output up to 25 A / 82.5 W Synchronization Synchronization is a feature that allows multiple products to be synchronized to a common frequency. Synchronized products powered from the same bus eliminate beat frequencies reflected back to the input supply, and also reduces EMI filtering requirements. Eliminating the slow beat frequencies (usually <10 kHz) allows the EMI filter to be designed to attenuate only the synchronization frequency. Synchronization can also be utilized for phase spreading, described in section Phase Spreading. The products can be synchronized with an external oscillator or one product can be configured with the SYNC pin as a SYNC Output working as a master driving the synchronization. All others on the same synchronization bus must be configured with SYNC Input. Default configuration is using the internal clock, independently of signal at the SYNC pin. See application note AN309 for further information. Phase Spreading When multiple products share a common DC input supply, spreading of the switching clock phase between the products can be utilized. This dramatically reduces input capacitance requirements and efficiency losses, since the peak current drawn from the input supply is effectively spread out over the whole switch period. This requires that the products are synchronized. Up to 16 different phases can be used. The phase spreading of the product can be configured using the PMBus interface. See application note AN309 for further information. Parallel Operation (Current Sharing) Paralleling multiple products can be used to increase the output current capability of a single power rail. By connecting the GCB pins of each device and configuring the devices as a current sharing rail, the units will share the current equally, enabling up to 100% utilization of the current capability for each device in the current sharing rail. The product uses a lowbandwidth, first-order digital current sharing by aligning the output voltage of the slave devices to deliver the same current as the master device. Artificial droop resistance is added to the output voltage path to control the slope of the load line curve, calibrating out the physical parasitic mismatches due to power train components and PWB layout. Up to 7 devices can be configured in a given current sharing group. See application note AN307 for further information. Phase Adding and Shedding for Parallel Operation During periods of light loading, it may be beneficial to disable one or more phases (modules) in order to eliminate the current drain and switching losses associated with those phases, resulting in higher efficiency. The product offers the ability to add and drop phases (modules) using a PMBus command in response to an observed load current change. All phases (modules) in a current share rail are considered active prior to the current sharing rail ramp to power-good. Phases can be dropped after power-good is reached. Any member of the current sharing rail can be dropped. If the reference module is dropped, the remaining active module with the lowest member TechnicalReference Specification Date Rev 2014-02-11 EN/LZT 146 434 R4B February 2014 D 46 (c) Ericsson AB position will become the new reference. Additionally, any change to the number of members of a current sharing rail will precipitate autonomous phase distribution within the rail where all active phases realign their phase position based on their order within the number of active members. If the members of a current sharing rail are forced to shut down due to an observed fault, all members of the rail will attempt to re-start simultaneously after the fault has cleared. See application note AN307 for further information. Efficiency Optimized Dead Time Control The product utilizes a closed loop algorithm to optimize the dead-time applied between the gate drive signals for the switch and synch FETs. The algorithm constantly adjusts the deadtime non-overlap to minimize the duty cycle, thus maximizing efficiency. This algorithm will null out deadtime differences due to component variation, temperature and loading effects. The algorithm can be configured via the PMBus interface. Over Current Protection (OCP) The product includes current limiting circuitry for protection at continuous overload. The following OCP response options are available: 1. Initiate a shutdown and attempt to restart an infinite number of times with a preset delay period between attempts. 2. Initiate a shutdown and attempt to restart a preset number of times with a preset delay period between attempts. 3. Continue operating for a given delay period, followed by shutdown if the fault still exists. 4. Continue operating through the fault (this could result in permanent damage to the power supply). 5. Initiate an immediate shutdown. The default response from an over current fault is an immediate shutdown of the device. The device will continuously check for the presence of the fault condition, and if the fault condition no longer exists the device will be reenabled. The load distribution should be designed for the maximum output short circuit current specified. The OCP limit and response of the product can be reconfigured using the PMBus interface. Initialization Procedure The product follows a specific internal initialization procedure after power is applied to the VIN pin: 1. Status of the address and output voltage pin-strap pins are checked and values associated with the pin settings are loaded to RAM. 2. Values stored in the Ericsson default non-volatile memory are loaded to RAM. This overwrites any previously loaded values. 3. Values stored in the user non-volatile memory are loaded to RAM. This overwrites any previously loaded values. Ericsson Internal PRODUCT SPECIFICATION E Prepared (also subject responsible if other) 7 (18) No. EAB/FJB/GMF EHOSMIR 47 30/1301-BMR 463 Uen Approved Checked BMR 463 series POL Regulators (EKRIROB) EAB/FJB/GMF (Ksenia Harrisen) Input 4.5-14 V, Output up to 25 A / 82.5 W Once the initialization process is completed, the product is ready to be enabled using the CTRL pin. The product is also ready to accept commands via the PMBus interface, which will overwrite any values loaded during the initialization procedure. Soft-start Power Up The soft-start control introduces a time-delay before allowing the output voltage to rise. Once the initialization time has passed the device will wait for the configured delay period prior to starting to ramp its output. After the delay period has expired, the output will begin to ramp towards its target voltage according to the configured soft-start ramp time. The default settings for the soft-start delay period and the softstart ramp time is 10 ms. Hence, power-up is completed within 20 ms in default configuration using remote control. When the soft-start delay time is set to 0 ms, the module will begin its ramp-up after the internal circuitry has initialized (approximately 2 ms). It is generally recommended to set the soft-start ramp-up time to a value greater than 500 s to prevent inadvertent fault conditions due to excessive inrush current. The acctual minimum ramp-up time will however normally be limited by the control loop settings and ramp-up times of internal interface voltages in the controller circuit to approximatley 2 ms. The soft-start power up of the product can be reconfigured using the PMBus interface.

Voltage Tracking The product integrates a lossless tracking scheme that allows its output to track a voltage that is applied to the VTRK pin with no external components required. During ramp-up, the output voltage follows the VTRK voltage until the preset output voltage level is met. The product offers two modes of tracking as follows: 1. Coincident. This mode configures the product to ramp its output voltage at the same rate as the voltage applied to the VTRK pin. VIN VOUT CTRL MASTER VOUT Initialization time Delay time Ramp time Illustration of Power Up Procedure. Output Voltage Sequencing A group of products may be configured to power up in a predetermined sequence. This feature is especially useful when powering advanced processors, FPGAs, and ASICs that require one supply to reach its operating voltage prior to another. Multi-product sequencing can be achieved by configuring the start delay and rise time of each device through the PMBus interface and by using the CTRL start signal. See application note AN310 for further information. SLAVE t Illustration of Coincident Voltage Tracking. Ericsson Internal PRODUCT SPECIFICATION E Prepared (also subject responsible if other) EAB/FJB/GMF EHOSMIR Approved 8 (18) No. 30/1301-BMR 463 Uen Checked BMR 463 series POL Regulators (EKRIROB) EAB/FJB/GMF (Ksenia Harrisen) Input 4.5-14 V, Output up to 25 A / 82.5 W 2. Ratiometric. This mode configures the product to ramp its output voltage at a rate that is a percentage of the voltage applied to the VTRK pin. The default setting is 50%, but a different tracking ratio may be set by an external resistive voltage divider or through the PMBus interface. VOUT MASTER SLAVE t Illustration of Ratiometric Voltage Tracking The master device in a tracking group is defined as the device that has the highest target output voltage within the group. This master device will control the ramp rate of all tracking devices and is not configured for tracking mode. All of the CTRL pins in the tracking group must be connected and driven by a single logic source. It should be noted that current sharing groups that are also configured to track another voltage do not offer pre-bias protection; a minimum load should therefore be enforced to avoid the output voltage from being held up by an outside force. See application note AN310 for further information. Voltage Margining Up/Down The product can adjust its output higher or lower than its nominal voltage setting in order to determine whether the load device is capable of operating over its specified supply voltage range. This provides a convenient method for dynamically testing the operation of the load circuit over its supply margin or range. It can also be used to verify the function of supply voltage supervisors. Margin limits of the nominal output voltage 5% are default, but the margin limits can be reconfigured using the PMBus interface. Pre-Bias Startup Capability Pre-bias startup often occurs in complex digital systems when current from another power source is fed back through a dualsupply logic component, such as FPGAs or ASICs. The BMR463 product family incorporates synchronous rectifiers, but will not sink current during startup, or turn off, or whenever a fault shuts down the product in a pre-bias condition. Pre-bias protection is not offered for current sharing groups that also have voltage tracking enabled. TechnicalReference Specification Date Rev 2014-02-11 EN/LZT 146 434 R4B February 2014 D 48 (c) Ericsson AB Group Communication Bus The Group Communication Bus, GCB, is used to communicate between products. This dedicated bus provides the communication channel between devices for features such as sequencing, fault spreading, and current sharing. The GCB solves the PMBus data rate limitation. The GCB pin on all devices in an application should be connected together. A pullup resistor is required on the common GCB in order to guarantee the rise time as follows: Eq. 5. RGCB CGCB 1 s , where RGCB is the pull up resistor value and CGCB is the bus loading. The pull-up resistor should be tied to an external supply voltage in range from 3.3 to 5 V, which should be present prior to or during power-up. If exploring untested compensation or deadtime configurations, it is recommended that 27 series resistors are placed between the GCB pin of each product and the common GCB connection. This will avoid propagation of faults between products potentially caused by hazardous configuration settings. When the configurations of the products are settled the series resistors can be removed. The GCB is an internal bus, such that it is only connected across the modules and not the PMBus system host. GCB addresses are assigned on a rail level, i.e. modules within the same current sharing group share the same GCB address. Addressing rails across the GCB is done with a 5 bit GCB ID, yielding a theoretical total of 32 rails that can be shared with a single GCB bus. See application note AN307 for further information. Fault spreading The product can be configured to broadcast a fault event over the GCB bus to the other devices in the group. When a nondestructive fault occurs and the device is configured to shut down on a fault, the device will shut down and broadcast the fault event over the GCB bus. The other devices on the GCB bus will shut down together if configured to do so, and will attempt to re-start in their prescribed order if configured to do so. Over Temperature Protection (OTP) The products are protected from thermal overload by an internal over temperature shutdown function in the controller circuit N1, located at position P2 (see section Thermal Consideration). Some of the products that this specification covers use the temperature at position P2 (TP2) as a reference for OTP and some use position P1 (TP1) as a reference for OTP. See the Over Temperature Protection section in the electrical specification for each product. Products with P1 as reference for OTP: When TP1 as defined in thermal consideration section exceeds approximately 120 C the product will shut down. The specified OTP level and hysteresis are valid for worst case operation regarding cooling conditions, input voltage and output voltage. The actually configured default value in the controller circuit in position P2 is 110 C, but at worst case operation the Ericsson Internal PRODUCT SPECIFICATION E Prepared (also subject responsible if other) EAB/FJB/GMF EHOSMIR Checked BMR 463 series POL Regulators (EKRIROB) EAB/FJB/GMF (Ksenia Harrisen) Input 4.5-14 V, Output up to 25 A / 82.5 W temperature is approximately 10 C higher at position P1. At light load the temperature is approximately the same in position P1 and P2. This means the OTP level and hysteresis will be lower at light load conditions when P1 is used as reference for OTP. Products with P2 as reference OTP: When TP2 as defined in thermal consideration section exceeds 120 C the product will shut down. For products with P2 as a reference for OTP the configured default value in the controller circuit in position P2 is 120 C.

Cooling is achieved mainly by conduction, from the pins to the host board, and convection, which is dependent on the airflow across the product. Increased airflow enhances the cooling of the product. The Output Current Derating graph found in the Output section for each model provides the available output current vs. ambient air temperature and air velocity at specified VI. Bottom view Top view P2 P1 Temperature positions and air flow direction. SIP version The product is tested on a 254 x 254 mm, 35 m (1 oz), test board mounted vertically in a wind tunnel with a cross-section of 608 x 203 mm. The test board has 8 layers. Proper cooling of the product can be verified by measuring the temperature at positions P1 and P2. The temperature at these positions should not exceed the max values provided in the table below. Note that the max value is the absolute maximum rating (non destruction) and that the electrical Output data is guaranteed up to TP1 +95 C. AIR FLOW P1 P2 Temperature positions and air flow direction. See Design Note 019 for further information. Definition of product operating temperature The product operating temperatures are used to monitor the temperature of the product, and proper thermal conditions can be verified by measuring the temperature at positions P1 and P2. The temperature at these positions (TP1, TP2) should not exceed the maximum temperatures in the table below. The number of measurement points may vary with different thermal design and topology. Temperatures above maximum TP1, measured at the reference point P1 are not allowed and may cause permanent damage. It should also be noted that depending on setting of the over temperature protection (OTP) and operating conditions, the product may shut down before the maximum allowed temperature at TP1 is reached.

The product can be used with any standard two-wire I2C or SMBus host device. In addition, the product is compatible with PMBus version 1.1 and includes an SALERT line to help mitigate bandwidth limitations related to continuous fault monitoring. The product supports 100 kHz bus clock frequency only. The PMBus signals, SCL, SDA and SALERT require passive pull-up resistors as stated in the SMBus Specification. Pull-up resistors are required to guarantee the rise time as follows: This product offers a special feature that enables the user to capture parametric data during normal operation or following a fault. The following parameters are stored: Eq. 6 RP C p 1s where Rp is the pull-up resistor value and Cp is the bus loading, the maximum allowed bus load is 400 pF. The pull-up resistor should be tied to an external supply voltage in range from 2.7 to 5.5 V, which should be present prior to or during power-up. If the proper power supply is not available, voltage dividers may be applied. Note that in this case, the resistance in the equation above corresponds to parallel connection of the resistors forming the voltage divider. See application note AN304 for details on interfacing the product with a microcontroller. Monitoring via PMBus It is possible to monitor a wide variety of parameters through the PMBus interface. Fault conditions can be monitored using the SALERT pin, which will be asserted when any number of pre-configured fault or warning conditions occurs. It is also possible to continuously monitor one or more of the power conversion parameters including but not limited to the following: Input voltage (READ_VIN) Output voltage (READ_VOUT) Output current (READ_IOUT) Internal junction temperature (READ_TEMPERATURE_1) Switching frequency (READ_FREQUENCY) Duty cycle (READ_DUTY_CYCLE) In the default configuration monitoring is enabled also when the output voltage is disabled. This can be changed in order to reduce standby power consumption. Input voltage Output voltage Output current Internal junction temperature Switching frequency Duty cycle Status registers The Snapshot feature enables the user to read the parameters via the PMBus interface during normal operation, although it should be noted that reading the 22 bytes will occupy the bus for some time. The Snapshot enables the user to store the snapshot parameters to Flash memory in response to a pending fault as well as to read the stored data from Flash memory after a fault has occurred. Automatic store to Flash memory following a fault is triggered when any fault threshold level is exceeded, provided that the specific fault response is to shut down. Writing to Flash memory is not allowed if the device is configured to restart following the specific fault condition. It should also be noted that the device supply voltage must be maintained during the time the device is writing data to Flash memory; a process that requires between 700-1400 s depending on whether the data is set up for a block write. Undesirable results may be observed if the input voltage of the product drops below 3.0 V during this process.

This product does not support the BUSY flag in the status commands to indicate product being too busy for SMBus response. Instead a bus-free time delay according to this specification must occur between every SMBus transmission (between every stop & start condition). In case of storing the RAM content into the internal non-volatile memory (commands STORE_USER_ALL and STORE_DEFAULT_ALL) an additional delay of 100 ms has to be inserted. A 100 ms delay should be inserted after a restore from internal non-volatile memory (commands RESTORE_DEFAULT_ALL and RESTORE_USER_ALL).

The reflow profile should be optimised to avoid excessive heating of the product. It is recommended to have a sufficiently extended preheat time to ensure an even temperature across the host PWB and it is also recommended to minimize the time in reflow. A no-clean flux is recommended to avoid entrapment of cleaning fluids in cavities inside the product or between the product and the host board, since cleaning residues may affect long time reliability and isolation voltage. 2013-10-30 Specification Rev Reference B Template rev. J 66 EN/LZT 146 434 R4B February 2014 (c) Ericsson AB Lead-free (Pb-free) solder processes For Pb-free solder processes, a pin temperature (TPIN) in excess of the solder melting temperature (TL, 217 to 221C for SnAgCu solder alloys) for more than 60 seconds and a peak temperature of 245C on all solder joints is recommended to ensure a reliable solder joint. Maximum Product Temperature Requirements Top of the product PWB near pin 4B is chosen as reference location for the maximum (peak) allowed product temperature (TPRODUCT) since this will likely be the warmest part of the product during the reflow process.

During reflow TPRODUCT must not exceed 260 C at any time. Dry Pack Information Products intended for Pb-free reflow soldering processes are delivered in standard moisture barrier bags according to IPC/JEDEC standard J-STD-033 (Handling, packing, shipping and use of moisture/reflow sensitivity surface mount devices). Using products in high temperature Pb-free soldering processes requires dry pack storage and handling. In case the products have been stored in an uncontrolled environment and no longer can be considered dry, the modules must be baked according to J-STD-033. Thermocoupler Attachment Pin 2A for measurement of minimum Pin (solder joint) temperature TPIN SnPb solder processes For SnPb solder processes, a pin temperature (TPIN) in excess of the solder melting temperature, (TL, 183C for Sn63Pb37) for more than 60 seconds and a peak temperature of 220C is recommended to ensure a reliable solder joint. For dry packed products only: depending on the type of solder paste and flux system used on the host board, up to a recommended maximum temperature of 245C could be used, if the products are kept in a controlled environment (dry pack handling and storage) prior to assembly.
