General Information Reliability The failure rate () and mean time between failures (MTBF= 1/) is calculated at max output power and an operating ambient temperature (TA) of +40C. Ericsson Power Modules uses Telcordia SR-332 Issue 2 Method 1 to calculate the mean steady-state failure rate and standard deviation (). Telcordia SR-332 Issue 2 also provides techniques to estimate the upper confidence levels of failure rates based on the mean and standard deviation. Mean steady-state failure rate, Std. deviation, 425 nFailures/h 60.9 nFailures/h MTBF (mean value) for the BMR456 series = 2.9 Mh.

IEC/EN/UL 60950-1 contains requirements to prevent injury or damage due to the following hazards: 4 (5) 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/EN/UL 60950-1 Safety of Information Technology Equipment. Product related standards, e.g. IEEE 802.3af Power over Ethernet, and ETS-300132-2 Power interface at the input to telecom equipment, operated by direct current (dc) 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. Isolated DC/DC converters Galvanic isolation between input and output is verified in an electric strength test and the isolation voltage (Viso) meets the voltage strength requirement for basic insulation according to IEC/EN/UL 60950-1. It is recommended to use a slow blow fuse 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 Rev Reference 4 1/28701-FGC 101 1823 revD February 2013 D (c) Ericsson AB 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 DC/DC converter output is considered as safety extra low voltage (SELV) if one of the following conditions is met: The input source has double or reinforced insulation from the AC mains according to IEC/EN/UL 60950-1 The input source has basic or supplementary insulation from the AC mains and the input of the DC/DC converter is maximum 60 Vdc and connected to protective earth according to IEC/EN/UL 60950-1 The input source has basic or supplementary insulation from the AC mains and the DC/DC converter output is connected to protective earth according to IEC/EN/UL 60950-1 Non - isolated DC/DC regulators The DC/DC regulator output is SELV if the input source meets the requirements for SELV circuits according to IEC/EN/UL 60950-1.

The remote control functions can also be configured using the PMBus 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, duty cycle and internal temperature. The device should be capable of sinking 0.7 mA. When the RC pin is left open, the voltage generated on the RC pin is max 6 V. The standard product is provided with "negative logic" remote control and will be off until the RC pin is connected to the -In. To turn on the product the voltage between RC pin and -In should be less than 1 V. 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 down-load of your own configurations. To turn off the product the RC pin should be left open for a minimum of time 150 s, the same time requirement applies when the product shall turn on. In situations where it is desired to have the product to power up automatically without the need for control signals or a switch, the RC pin can be wired directly to -In or disabled via the 0xE3 command. The logic option for the primary remote control is configured via 0xE3 command using the PMBus. Input Voltage The BMR456 consists of two different product families designed for two different input voltage ranges, 36 to 75 Vdc and 40 to 60 Vdc, see ordering information. Remote Control (secondary side) The CTRL-pin can be configured as remote control via the PMBus interface. In the default configuration the CTRL-pin is disabled and floating. The output can be configured to internal pull-up to 3.3 V using the MFR_MULTI_PIN_CONFIG (0xF9) PMBus command. The CTRL-pin can be left open when not used. The logic options for the secondary remote control can be positive or negative logic. The logic option for the secondary remote control is configured via ON_OFF_CONFIG (0x02) command using the PMBus interface, see also MFR_MULTI_PIN_CONFIG section. The input voltage range 36 to 75 Vdc meets the requirements of the European Telecom Standard ETS 300 132-2 for normal input voltage range in -48 and -60 Vdc systems, -40.5 to -57.0 V and -50.0 to -72 V respectively. At input voltages exceeding 75 V, the power loss will be higher than at normal input voltage and TP1 must be limited to absolute max +125C. The absolute maximum continuous input voltage is 80 Vdc. The input voltage range 40 to 60 Vdc meets the requirements for normal input voltage range in -48 V systems, -40.5 to -57.0 V. At input voltages exceeding 60 V, the power loss will be higher than at normal input voltage and TP1 must be limited to absolute max +125C. The absolute maximum continuous input voltage is 65 Vdc. Turn-off Input Voltage The product monitors the input voltage and will turn on and turn off at predetermined levels. The minimum hysteresis between turn on and turn off input voltage is 2 V. The turn on and turn off levels of the product can be reconfigured using the PMBus interface Remote Control (RC) The products are fitted with a configurable remote control function. The primary remote control is referenced to the primary negative input connection (-In). The RC function allows the converter to be turned on/off by an external device like a semiconductor or mechanical switch. The RC pin has an 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. Minimum recommended external input capacitance is 100 F. The electrolytic capacitors will be degraded in low temperature. The input capacitance in low temperature should be equivalent to 100 F in 20degree. The performance in some applications can be enhanced by addition of external capacitance as described under External Decoupling Capacitors. External Decoupling 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 parallel capacitors 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 Ericsson Internal PRODUCT SPECIFICATION E Prepared (also subject responsible if other) No. 30/1301-BMR 456 Uen Technical Specification 35 EMAOLII Approved Checked Date BMR456 series Bus Converters SEC/D (Julia You) Fully regulated Advanced EZHIXZH 2013-02-06 Input 36-75 V, Output up to 39 A / 468 W also reduce any high frequency noise at the load. It is equally important to use low resistance and low inductance PWB layouts and cabling. External decoupling capacitors will become part of the product's control loop. The control loop is optimized for a wide range of external capacitance and the maximum recommended value that could be used without any additional analysis is found in the electrical specification. The ESR of the capacitors is a very important parameter. Stable operation is guaranteed with a verified ESR value of >10 m across the output connections. For further information please contact your local Ericsson Power Modules representative. Parallel Operation (Droop Load Share, DLS) The BMR456, DLS products, (product-number ending /013, /014, /016 or /017) are variants that can be connected in parallel. The products have a pre-configured voltage droop: The stated output voltage set point is at no load. The output voltage will decrease when the load current is increased. The voltage will droop 0.6 V while load reaches max load. This feature allows the products to be connected in parallel and share the current with 10% accuracy. Up to 90% of max output current can be used from each product. When running DLS-products in parallel command (0xF9) must be set according to MFR_MULTI_PIN_CONFIG. To prevent unnecessary current stress, changes of the output voltage must be done with the output disabled. This must be considered for all commands that affect the output voltage. Voltage regulation DLS products Output Voltage [V] 12.8 Module 1 12.6 Module 2 Module 1+2 12.4 12.2 12.0 11.8 11.6 0 10 20 30 40 50 60 3 (8) 70 Output Current [A] Feed Forward Capability The BMR456 products have a feed forward function implemented that can handle sudden input voltage changes. The output voltage will be regulated during an input transient and will typically stay within 10% when an input transient is applied. PMBus configuration and support The product provides a PMBus digital interface that enables the user to configure many aspects of the device operation as well as monitor the input and output parameters. Rev Reference 1/28701-FGC 101 1823 revD February 2013 F (c) Ericsson AB Please contact your local Ericsson Power Modules representative for appropriate SW tools to down-load new configurations. Output Voltage Adjust using PMBus The output voltage of the product can be reconfigured using the PMBus interface. Margin Up/Down Controls These controls allow the output voltage to be momentarily adjusted, either up or down, by a nominal 10%. 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. The margin up and down levels of the product can be reconfigured using the PMBus interface. Soft-start Power Up The default rise time of the ramp up is 10 ms. When starting by applying input voltage the control circuit boot-up time adds an additional 15 ms delay. The soft-start power up of the product can be reconfigured using the PMBus interface. The DLS variants have a pre-configured ramp up time of 25 ms. 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. The remote sense circuitry will compensate for up to 10% voltage drop between output pins and the point of load. If the remote sense is not needed +Sense should be connected to +Out and -Sense should be connected to -Out. To be able to use remote sense the converter must be equipped with a Communication interface. Temperature Protection (OTP, UTP) The products are protected from thermal overload by an internal temperature shutdown protection. When TP1 as defined in thermal consideration section is exceeded the product will shut down. The product will make continuous attempts to start up (non-latching mode) and resume normal operation automatically when the temperature has dropped below the temperature threshold set in the command OT_WARN_LIMIT (0x51); the hysteresis is defined in general electrical specification. The OTP and hysteresis of the product can be re-configured using the PMBus interface. The product has also an under temperature protection. The OTP and UTP fault limit and fault response can be configured via the PMBus. Note: using the fault response "continue without interruption" may cause permanent damage to the product Over Voltage Protection (OVP) The product includes over voltage limiting circuitry for protection of the load. The default OVP limit is 30% above the nominal output voltage.

For products mounted on a PWB without a heat sink attached, cooling is achieved mainly by conduction, from the pins to the host board, and convection, which is dependant 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 VI =53 V. The product is tested on a 254 x 254 mm, 35 m (1 oz), 16-layer test board mounted vertically in a wind tunnel with a cross-section of 608 x 203 mm. For products with base plate used in a sealed box/cold wall application, cooling is achieved mainly by conduction through the cold wall. The Output Current Derating graphs are found in the output section for each model. The product is tested in a sealed box test set up with ambient temperatures 85, 55 and 25C. See Design Note 028 for further details. Definition of product operating temperature The product operating temperature is used to monitor the temperature of the product, and proper thermal conditions can be verified by measuring the temperature at positions P1, P2, P3 and P4. The temperature at these positions (TP1, TP2, TP3, TP4) should not exceed the maximum temperatures in the table below. The number of measurement points may vary with different thermal design and topology.

The product can be used with any standard two-wire I2C or SMBus host device. In addition, the product is compatible with PMBus version 1.2 and includes an SALERT line to help mitigate bandwidth limitations related to continuous fault monitoring. The product supports 100 kHz and 400 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: Eq. 7 = R P C p 1us where Rp is the pull-up resistor value and Cp is the bus load. The maximum allowed bus load is 400 pF. The pull-up resistor should be tied to an external supply between 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. Schematic of connection of address resistors. SA0/SA1 Index 0 It is recommended to always use PEC (Packet Error Check) when communicating via PMBus. For these products it is a requirement to use PEC when using Send Byte to the device, for example command "RESTORE_DEFAULT_ALL". Monitoring via PMBus A system controller (host device) can monitor a wide variety of parameters through the PMBus interface. The controller can monitor fault conditions by monitoring the SALERT pin, which will be asserted when any number of pre-configured fault or warning conditions occur. The system controller can also continuously monitor any number of power conversion parameters including but not limited to the following: * * * * * * Input voltage Output voltage Output current Internal junction temperature Switching frequency (Monitors the set value not actual frequency) Duty cycle Software Tools for Design and Production For this products Ericsson provides software for configuring and monitoring via the PMBus interface. For more information please contact your local Ericsson sales representative. PMBus Addressing The following figure and table show recommended resistor values with min and max voltage range for hard-wiring PMBus addresses (series E12, 1% tolerance resistors suggested): RSA0/RSA1 [k] 10 1 22 2 33 3 47 4 68 5 100 6 150 7 220 The SA0 and SA1 pins can be configured with a resistor to GND according to the following equation. PMBus Address = 8 x (SA0value) + (SA1 value) If the calculated PMBus address is 0, 11 or 12, PMBus address 127 is assigned instead. From a system point of view, the user shall also be aware of further limitations of the addresses as stated in the PMBus Specification. It is not recommended to keep the SA0 and SA1 pins left open. I2C/SMBus - Timing Setup and hold times timing diagram The setup time, tset, is the time data, SDA, must be stable before the rising edge of the clock signal, SCL. The hold time thold, is the time data, SDA, must be stable after the rising edge of the clock signal, SCL. If these times are violated incorrect data may be captured or meta-stability may occur and the bus communication may fail. When configuring the product, all standard SMBus protocols must be followed, including clock Ericsson Internal PRODUCT SPECIFICATION E Prepared (also subject responsible if other) 31/1301-BMR 456+ Uen Technical Specification 41 SECSUND Approved 2 (4) No. Checked Date BMR456 series SEC/D (Julia You) Fully regulated Advanced EMAOLIIBus Converters 2012-06-25 Input 36-75 V, Output up to 39 A / 468 W stretching. Additionally, a bus-free time delay between every SMBus transmission (between every stop & start condition) must occur. Refer to the SMBus specification, for SMBus electrical and timing requirements. Note that an additional delay of 5 ms has to be inserted in case of storing the RAM content into the internal non-volatile memory.

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. 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.

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 Minimum Pin Temperature Recommendations Pin number 5 chosen as reference location for the minimum pin Top of PWB near pin 2 for measurement of maximum product temperature, TPRODUCT temperature recommendation since this will likely be the coolest solder joint during the reflow process. 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.
