Reliability The Mean Time Between Failure (MTBF) is calculated at full output power and an operating ambient temperature (TA) of +40C, which is a typical condition in Information and Communication Technology (ICT) equipment. Different methods could be used to calculate the predicted MTBF and failure rate which may give different results. Ericsson Power Modules currently uses one method Telcordia SR332. Predicted MTBF for the series is: BMR 640 5002: 3.34 million hours According to Telcordia SR332, issue 1, Black box technique. The Ericsson failure rate data system is based on field tracking data. The data corresponds to actual failure rates of components used in Information Technology and Telecom (IT&T) equipment in temperature controlled environments (TA = -5...+65C). Telcordia SR332 is a commonly used standard method intended for reliability calculations in IT&T equipment. The parts count procedure used in this method was originally modelled on the methods from MIL-HDBK-217F, Reliability Predictions of Electronic Equipment. It assumes that no reliability data is available on the actual units and devices for which the predictions are to be made, i.e. all predictions are based on generic reliability parameters.

IEC/EN/UL60950 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 are defined as component power supplies. As components they cannot fully comply with the provisions of any Safety requirements without "Conditions of Acceptability". 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 Directives for the final product. Component power supplies for general use should comply with the requirements in IEC60950, EN60950 and UL60950 "Safety of information technology equipment". There are other more product related standards, e.g. IEEE802.3af "Ethernet LAN/MAN Data terminal equipment power", and ETS300132-2 "Power supply interface at the input to telecommunications equipment; part 2: DC", but all of these standards are based on IEC/EN/UL60950 with regards to safety. The flammability rating for all construction parts of the products meets requirements for V-0 class material according to IEC 60695-11-10. 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/UL60950. Isolated DC/DC converters It is recommended that a slow blow fuse with a rating twice the maximum input current per selected product 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 in the input filter or in the DC/DC converter that imposes a short circuit on the input source, this fuse will provide the following functions: * * Isolate the faulty DC/DC converter 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 500 Vdc for 60 seconds (refer to product specification). Leakage current is less than 1 A at nominal input voltage. 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 Ericsson Power Modules 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 TNV2 circuit and testing has demonstrated compliance with SELV limits and isolation requirements equivalent to Basic Insulation in accordance with IEC/EN/UL60950. 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.

Input And Output Impedance The impedance of both the input source and the load will interact with the impedance of the DC/DC converter. It is important that the input source has low characteristic impedance. The converters are designed for stable operation without external capacitors connected to the input or output. 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 significant inductance, the addition of a 10 F capacitor across the input of the converter will ensure stable operation. The capacitor is not required when powering the DC/DC converter from an input source with an inductance below 10 H. 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 by 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 at the load. It is equally important to use low resistance and low inductance PCB layouts and cabling. External decoupling capacitors will become part of the control loop of the DC/DC converter and may affect the stability margins. As a "rule of thumb", 100 F/A of output current can be added without any additional analysis. The recommended absolute maximum value of output capacitance is 5 000 F. For further information please contact your local Ericsson Power Modules representative. Temperature Shutdown The DC/DC converters include an internal over temperature shutdown circuit. When the temperature exceeds 130C - 150C on the control circuit the converter will shut down. The DC/DC converter will make continuous attempts to start up (non-latching mode) and resume normal operation automatically when the temperature has dropped >15C below the temperature threshold. Synchronization (Sync) It is possible to synchronize the switching frequency on BMR 640 5002/1 by connecting the synchronization pins (pin 7) together. Over Current Protection (OCP) The converters include current limiting circuitry for protection at continuous overload. The output voltage will decrease towards zero for output currents in excess of max output current (max IO). The converter will resume normal operation after removal of the overload. The load distribution should be designed for the maximum output short circuit current specified.

Cooling is achieved mainly by conduction, from the pins to the PCB board, and convection, which is dependant on the airflow across the converter. Increased airflow enhances the cooling of the converter. 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 Vin = 53 V. Ambient Temperature Calculation By using the thermal resistance the maximum allowed ambient temperature can be calculated. 1. The power loss is calculated by using the formula ((1/) - 1) x output power = power losses (Pd). = efficiency of converter. E.g. 82.5 % = 0.825 2. Find the thermal resistance (Rth) in the Thermal Resistance graph found in the Output section for each model. Calculate the temperature increase (T). T = Rth x Pd The converter 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 305 x 305 mm. 3. Max allowed ambient temperature is: Max Tref - T. Proper cooling of the converter can be verified by measuring the temperature at position P1. The temperature at these positions should not exceed the max values provided in the table below. E.g. BMR 640 5002/1 at 1m/s: Note that the max value is the absolute maximum rating (non destruction) and that the electrical Output data is guaranteed up to Tref +95C.

(( 3. 110 C - 27.9 C = max ambient temperature is 82.1C The actual temperature will be dependent on several factors such as the PCB size, number of layers and direction of airflow.

To achieve a good and reliable soldering result, make sure to follow the recommendations from the solder paste supplier, to use state-of-the-art reflow equipment and reflow profiling techniques as well as the following guidelines. To avoid damage or performance degradation of the product, the reflow profile should be optimized to avoid excessive heating. The maximum product temperature shall be monitored by attaching a thermocoupler to the top of the main transformer. When using a Sn/Pb solder in the host board assembly process, the composition of the mix of Pb- and Pb-free solder results in a higher melting temperature compared to standard Pb solder. A no-clean flux is recommended to avoid entrapment of cleaning fluids in cavities inside the product. The cleaning residues may affect long time reliability and isolation voltage. Minimum pin temperature recommendations Pin number 5 and 14 are chosen as reference locations for the minimum pin temperature recommendations since these will be the coolest solder joints during the reflow process. A sufficiently extended preheat time is recommended to ensure an even temperature across the host PCB, for both small and large devices. To reduce the risk of excessive heating is also recommended to reduce the time in the reflow zone as much as possible.
