Exemptions in the RoHS directive utilized in Ericsson Power Modules products include: Lead in high melting temperature type solder (used to solder the die in semiconductor packages) Lead in glass of electronics components and in electronic ceramic parts (e.g. fill material in chip resistors) Lead as an alloying element in copper alloy containing up to 4% lead by weight (used in connection pins made of Brass) Reliability Quality Statement 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 Telcordia SR332. The products are designed and manufactured in an industrial environment where quality systems and methods like ISO 9000, 6 (sigma), and SPC are intensively in use to boost the continuous improvements strategy. Infant mortality or early failures in the products are screened out and they are subjected to an ATE-based final test. Conservative design rules, design reviews and product qualifications, plus the high competence of an engaged work force, contribute to the high quality of our products. Predicted MTBF for the series is: 1.61 million hours according to Telcordia SR332, issue 1, Black box technique. Telcordia SR332 is a commonly used standard method intended for reliability calculations in ICT 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. Compatibility with RoHS requirements The products are compatible with the relevant clauses and requirements of the RoHS directive 2002/95/EC and have a maximum concentration value of 0.1% by weight in homogeneous materials for lead, mercury, hexavalent chromium, PBB and PBDE and of 0.01% by weight in homogeneous materials for cadmium. Warranty Warranty period and conditions are defined in Ericsson Power Modules General Terms and Conditions of Sale. Limitation of Liability Ericsson Power Modules does not make any other warranties, expressed or implied including any warranty of merchantability or fitness for a particular purpose (including, but not limited to, use in life support applications, where malfunctions of product can cause injury to a person's health or life).

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. Ericsson Power Modules DC/DC converters and DC/DC regulators are UL60950 recognized and certified in accordance with EN60950. 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 1500 Vdc or 2250 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.

At input voltages exceeding 75 V, the power loss will be higher than at normal input voltage and Tref must be limited to absolute max +110C. The absolute maximum continuous input voltage is 80 Vdc. Turn-off Input Voltage The DC/DC converters monitor 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 1 V. On the 15 V version the minimum hysteresis between turn on and turn off input voltage is 3 V. Remote Control (RC) The products are fitted with a remote control function referenced to the primary negative input connection (- In), with negative and positive logic options available. 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 to + In. The maximum required sink current is 0.6 mA. When the RC pin is left open, the voltage generated on the RC pin is 10 -- 22 V. The maximum allowable leakage current of the switch is 50 A. With "negative logic" the converter will turn on when the input voltage is applied with the RC connected to the - In. Turn off is achieved by leaving the RC pin open, or connected to a voltage higher than 8 V referenced to --In. The second option is "positive logic" remote control, which can be ordered by adding the suffix "P" to the end of the part number. The converter will turn on when the input voltage is applied with the RC pin open. Turn off is achieved by connecting the RC pin to the - In. To ensure safe turn off the voltage difference between RC pin and the - In pin shall be less than 1 V. The converter will restart automatically when this connection is opened. See Design Note 021 for detailed information. 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 output. It is recommended to use an external capacitor of minimum 1 F on the the input. The performance in some applications can Rev Reference 30 EN/LZT 146 308 R3A R2B May 2007 E (c) Ericsson Power Modules AB 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 100 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, 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 ESR of the capacitors is a very important parameter. Ericsson Power Modules guarantee stable operation with a verified ESR value of >10 m across the output connections.

This pin can be used to adjust the output voltage above or below Output voltage initial setting. When increasing the output voltage, the voltage at the output pins (including any remote sense compensation ) must be kept below the threshold of the over voltage protection, (OVP) to prevent the converter from shutting down. At increased output voltages the maximum power rating of the converter remains the same, and the max output current must be decreased correspondingly. To increase the voltage the resistor should be connected between the Vadj pin and +Sense pin. The resistor value of the Output voltage adjust function is according to information given under the Output section for the respective product. To decrease the output voltage, the resistor should be connected between the Vadj pin and --Sense pin. Rev Reference 31 EN/LZT 146 308 R3A R2B May 2007 E (c) Ericsson Power Modules AB exceeds 135C the converter will shut down. The DC/DC converter will make continuous attempts to start up (nonlatching mode) and resume normal operation automatically when the temperature has dropped >5C below the temperature threshold. Over Voltage Protection (OVP) The converters have output over voltage protection that will shut down the converter in over voltage conditions. The converter will make continuous attempts to start up (nonlatching mode, hiccup) and resume normal operation automatically after removal of the over voltage condition. 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). If the output voltage decreases down to 0.5-0.6 V the converter shuts down and will make continuous attempts to start up (non-latching mode, hiccup). 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. 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. Typical Pre-bias source levels for no negative current: Parallel Operation Two converters may be paralleled for redundancy if the total power is equal or less than PO max. It is not recommended to parallel the converters without using external current sharing circuits. See Design Note 006 for detailed information. Remote Sense The DC/DC converters 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 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. Over Temperature Protection (OTP) The converters are protected from thermal overload by an internal over temperature shutdown circuit.

Cooling is achieved mainly by conduction, from the pins to the host board, and convection, which is dependent on the airflow across the converter. Increased airflow enhances the cooling of the converter. 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. For example 89.2 % = 0.892 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. 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 DC/DC 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 DC/DC converter can be verified by measuring the temperature at positions P1. The temperature at these positions should not exceed the max values provided in the table below. Example PKU 4510 (@ VI 53 V &15 A) at 1 m/s: 1. (( 1 ) - 1) x 49.5 W = 5.99 W 0.892 2. 5.99 W x 9.2C/W = 55.1C See Design Note 019 for further information. 3. 110 C -- 55.1C = max ambient temperature is 54.9C Position Device Designation Max value P1 Mosfet Tref 110C P1 Definition of reference temperature (Tref) The reference temperature is used to monitor the temperature limits of the product. Temperatures above maximum Tref are not allowed and may cause degradation or permanent damage to the product. Tref is also used to define the temperature range for normal operating conditions. Tref is defined by the design and used to guarantee safety margins, proper operation and high reliability of the module. 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. SnPb solder processes 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. Lead-free (Pb-free) solder processes Minimum Pin Temperature Recommendations Pin number 8 is chosen as reference location for the minimum pin temperature recommendations since this will likely be the coolest solder joint during the reflow process. Pin 8 for measurement of minimum solder joint temperature, TPIN For conventional SnPb solder processes, the product is qualified for MSL 1 according to IPC/JEDEC standard J-STD-020C. During reflow, TP must not exceed +225C at any time. For Pb-free solder processes, the product is qualified for MSL 3 according to IPC/JEDEC standard J-STD-020C. During reflow, TP must not exceed +260C at any time. Temperature Ramp-up TP Ramp-down (cooling) TL Reflow Preheat 25 C Time 25 C to peak Time Profile features Pin 2 for measurement of maximum peak product reflow temperature, TP SnPb solder processes For Pb solder processes, a pin temperature (TPIN) in excess of the solder melting temperature (TL, +183C for Sn63/Pb37) for more than 30 seconds, and a peak temperature of +210C is recommended to ensure a reliable solder joint. 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 Sn/Ag/Cu solder alloys) for more than 30 seconds, and a peak temperature of +235C on all solder joints is recommended to ensure a reliable solder joint. Sn/Pb eutectic assembly Average ramp-up rate Pb-free assembly 3C/s max 3C/s max TL +183C +221C Peak product temperature TP +225C +260C Average ramp-down rate 6C/s max 6C/s max Time 25 C to peak temperature 6 minutes max 8 minutes max Solder melting temperature (typical) Soldering Information -- Through Hole Mounting The through hole mount version of the product is intended for manual or wave soldering. When wave soldering is used, the temperature on the pins is specified to maximum 270C for maximum 10 seconds. Peak Product Temperature Requirements Pin number 2 is chosen as reference location for the maximum (peak) allowed product temperature, (TP), since this will likely be the warmest part of the product during the reflow process. To avoid damage or performance degradation of the product, the reflow profile should be optimized to avoid excessive heating. 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 it is also recommended to reduce the time in the reflow zone as much as possible. A maximum preheat rate of 4C/s and temperature of max 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 second s 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. E Ericsson Internal PROD.
