IEC/EN/UL 60950-1 contains requirements to prevent injury or damage due to the following hazards: 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 (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.

Note 2: It is recommended that a PMBus master read back written data for verification i.e. do not rely on the ACK/NACK bit since this bit are as susceptible to errors as any other bit*. However, under very rare operating conditions, it is possible to get intermittent read back failures. It is therefore recommended to implement error handling in the master that also deals with those situations.

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. Turn-off Input Voltage The product monitors the input voltage and will turn on and turn off at predetermined levels. The turn on and turn off level and the hysteresis in between can be configured via the PMBus. The default hysteresis between turn on and turn off input voltage is set to 2 V. Remote Control (RC) The products are fitted with a configurable remote control function on the primary and secondary side. 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 internal pull up resistor. The remote control functions can also be configured using the PMBus. 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. To turn off the product the RC pin should be left open. 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. The logic option for the primary remote control is configured using the PMBus. Remote Control (secondary side) The CTRL CS pin can be configured as remote control via the PMBus interface. In the default configuration the CTRL CS pin is disabled and the output has an internal pull-up to 3.3 V. The CTRL CS pin can be left open when not used. The logic options for the secondary remote control can be positive or negative logic. 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 (c) Ericsson AB the input source has low characteristic impedance. Minimum recommended external input capacitance is 100 uF. 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 recommended minimum capacitance on the output is 100 uF. 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 also reduce any high frequency noise across the load. 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 The products can be paralleled for redundancy if external oring diodes are used in series with the output. PMBus configuration and support The products provide 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. 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. Both BMR 454 0000/XXX and BMR 454 0004/005 can be adjusted from 8.1 V to 13.2 V. However, if output voltages above 11 V are desired at full load and at input below 40 V, the BMR4540004/005 should be used. When output voltages below 11V are desired or the limited input range (40-75 V) is acceptable, the BMR4540000/XXX is recommended for better efficiency and thermal performance. The BMR 454 0002/XXX can be adjusted from 3.0 V to 6.7 V at input voltages from 36 V to 75 V.

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 soft-start control introduces a time-delay (default setting 40 ms) before allowing the output voltage to rise. The default rise time of the ramp up is 10 ms. Power-up is hence completed within 50 ms in default configuration using remote control. When starting by applying input voltage the control circuit boot-up time adds an additional 100 ms delay. The softstart power up of the product can be reconfigured using the PMBus interface. Remote Sense The products have 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 PCB ground layer to reduce noise susceptibility. The remote sense circuitry will compensate for up to 10% voltage drop between +Out pin and the point of load (+Sense). The -Sense pin should be always connected to -Out. When activating remote sense, connect the +Sense pin to the +Input of the load. If the remote sense is not needed +Sense pin should be connected to +Out of the BMR454 unit. To be able to use remote sense the converter must be equipped with a digital connector. 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, 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 of the product. Over Voltage Protection (OVP) The product has output over voltage protection that will shut down the converter in over voltage conditions (latching mode) The OVP fault level and fault response can be re-configured using the PMBus interface. Over Current Protection (OCP) The product includes current limiting circuitry for protection at (c) Ericsson AB continuous overload. The module needs RC cycle operation at least once before enters hiccup mode if the maximum output current is exceeded and the output voltage is below 0.3xVout. The load distribution should be designed for the maximum output short circuit current specified. If for some reason the output should be short circuited, minimum resistance should not be lower than 6 m. The OCP level and fault response can be re-configured using the PMBus interface.The default configuration is set to hiccup mode for the OCP. Brick wall OCP mode is also supported in BMR454 series as option. For further information please contact your local Ericsson Power Modules representative. RC recycle operation as below: Vin RC_on RC_off RC_on RC_off Input Over/Under voltage protection The input of the product can be protected agains high input voltage and low input voltage. The over- and under-voltage fault level and fault response can be configured via the PMBus interface. Pre-bias Start-up The product has a Pre-bias start up functionality and will not sink current during start up if a pre-bias source is present at the output terminals. Synchronization When the PG SYNC pin is configured as an input (SYNC IN) the device will automatically check for a clock signal on the PG SYNC pin each time the module is enabled by RC or via PMBus. The incoming clock signal must be 150, 200 or 250 kHz and must be stable when the module is enabled. Note that PG SYNC pin is by default configured as Power Good output but may be reconfigured to SYNC IN via the PMBus interface. Power Good The PG SYNC pin is by default configured as Power Good output. The power good signal (TTL level) indicates proper operation of the product and can also be used as an error flag indicator. The Power Good signal is by default configured as active low and can be re-configured via the PMBus interface. Tracking and External reference The PG SYNC pin can be configured as an input for voltage tracking or an external analogue reference. The PG SYNC pin is configured via the PMBus interface and has default setting Power Good.

The product is optimized at this frequency but can run at lower and higher frequency, (150 kHz - 250 kHz). The electrical performance can be affected if the switching frequency is changed. Input Transient The BMR454 products have limited ability to react on sudden input voltage changes. As an example the 12 V module BMR454xxxx/001 can have an output voltage deviation of 5 V when a 20V input step is applied (40 V to 60 V). This is tested with a slew rate of 0.1 V/us on the input voltage change and minimum output capacitance 100 uF. Increasing the output capacitance will improve the result.

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), 8-layer test board mounted vertically in a wind tunnel with a cross-section of 608 x 203 mm. P3 P2 P4 P1 Top view Bottom view (Best airflow direction Negative to Positive.) Ambient Temperature Calculation For products with base plate the maximum allowed ambient temperature can be calculated by using the thermal resistance. 1. The power loss is calculated by using the formula ((1/) - 1) x output power = power losses (Pd). = efficiency of product. E.g. 95% = 0.95 2. Find the thermal resistance (Rth) in the Thermal Resistance graph found in the Output section for each model. Note that the thermal resistance can be significantly reduced if a heat sink is mounted on the top of the base plate. Calculate the temperature increase (T). T = Rth x Pd 3. Max allowed ambient temperature is: Max TP1 - T. Definition of product operating temperature The product operating temperatures is used to monitor the temperature of the product, and proper thermal conditions can be verified by measuring the temperature at positions P1, P2 and P3. The temperature at these positions (TP1, TP2 and TP3) 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. Position Description Max Temperature P1 PCB (Reference point) TP1=125 C P2 Opto-coupler TP2=105 C P3 PCB (Output inductor) TP3=125 C E.g. BMR 454 0100/001 at 1m/s: 1. (( 1 ) - 1) x 240 W = 15.3 W 0.94 2. 15.3 W x 4.1C/W = 63C 3. 125 C - 63C = max ambient temperature is 62C The actual temperature will be dependent on several factors such as the PCB size, number of layers and direction of airflow.

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.

Pb-free solder processes 6C/s max TL SnPb solder processes During reflow TPRODUCT must not exceed 225 C at any time. Average ramp-down (TPRODUCT) TPRODUCT maximum TPIN minimum Maximum Product Temperature Requirements Top of the product PWB near pin 2 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. Product profile Time For Pb-free solder processes, the product is qualified for MSL 3 according to IPC/JEDEC standard J-STD-020C. 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 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.

The pin temperature is specified to maximum to 270C for maximum 10 seconds. A maximum preheat rate of 4C/s and maximum preheat temperature of 150C is suggested. When soldering by hand, care should be taken to avoid direct contact between the hot soldering iron tip and the pins for more than a few seconds in order to prevent overheating. 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. The cleaning residues may affect long time reliability and isolation voltage. Delivery Package Information The products are delivered in antistatic injection molded trays (Jedec design guide 4.10D standard) and in antistatic trays.
