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: - 6.0 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. 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. 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) The exemption for lead in solder for servers, storage and storage array systems, network infrastructure equipment for switching, signaling, transmission as well as network management for telecommunication is only utilized in surface mount products intended for end-users' leaded SnPb Eutectic soldering processes. (See ordering information table). Quality Statement 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. 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). Ericsson Internal PRODUCT SPECIFICATION E Prepared (also subject responsible if other) SEC/S/ Stella TAO Approved PKR 2000A series SEC/S/ Stella TAO 3 (3) No. 1/1301-BMR6401211+ Uen Specification Technical Checked Date Rev (MICJOHN) 2007-09-18 DC/DC converters, Input 18-36 V, Output up to 2 A/15 W Reference 3 EN/LZT 146 352 R2C September 2007 D (c) Ericsson Power Modules AB Safety Specification General information Ericsson Power Modules DC/DC converters and DC/DC regulators are designed in accordance with safety standards IEC/EN/UL60950, Safety of Information Technology Equipment. 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 36 V, the power loss will be higher than at normal input voltage and Tref must be limited to absolute max +95C. The absolute maximum continuous input voltage is 36 Vdc. Turn-off Input Voltage The 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 0.6V. To increase VIon a resistor should be connected between pin 11 and 18. The resistance is given by the following equation: Rset(up) = (X - Von)/(Von - VIon) k To decrease VIon a resistor should be connected between pin 10 and 11.

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 10 000 F. For further information please contact your local Ericsson Power Modules representative. Output Voltage Adjust (Vadj) Voff is the adjusted turn-off input voltage and is determined by Von - Voff = 0.8V (Typical value). Remote Control (RC) The products are fitted with a remote control function referenced to the primary negative input connection (- In), and have positive logic. The RC function allows the converter to be turned on/off by an external device like a semiconductor or mechanical switch. The maximum required sink current is 1 mA. When the RC pin is left open, the voltage generated on the RC pin is <16 V. To ensure that the converter stays off the voltage must be below 1.0 V. 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. All converters have an Output Voltage Adjust pin (Vadj). This pin can be used to adjust the output voltage above or below Output voltage initial setting. 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 -IN. 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 NOR pin.

The load regulation characteristic is specifically designed for optimal paralleling performance. Load sharing between converters will be within 10%. It is recommended not to exceed PO = n x 0.9 x POmax, where POmax is the maximum converter output power and n is the number of paralleled converters, to prevent overloading any of the converters and thereby decreasing the reliability performance. The converters are designed to operate in different thermal environments and sufficient cooling must be provided to ensure reliable operation. 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 = 27 V. Over Temperature Protection (OTP) The PKR 2000A Series 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. 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. Over Current Protection (OCP) Note that the max value is the absolute maximum rating (non destruction) and that the electrical Output data is guaranteed up to Tref +95C. 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. Synchronization 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. See Design Note 019 for further information.

Mounting Options The surface mount version is available in two options, SnPb based or SnAgCu based (Pb-free) solder bumps. The SnPb solder bumps are intended for SnPb solder paste on the host board and to be reflowed in SnPb reflow process temperatures, typically +210 to +220C. The Pb-free solder bumps are intended for Pb-free solder paste on the host board and to be reflowed in Pb-free reflow process temperatures, typically +235 to +250C. Note that recommendations for minimum and maximum pin temperature -- and maximum peak product temperature -- are different depending on mounting option, reflow process type and if the dry packing of the products has been kept intact. General Reflow Profile Recommendations 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 PCB and 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. Rev Reference 24 EN/LZT 146 352 R2C September 2007 D (c) Ericsson Power Modules AB Mixed Solder Process Recommendations When using products with Pb-free solder bumps and thereby mixing Pb-free solder with SnPb paste on the host board and reflowing at SnPb process temperatures (backwards compatibility), special recommendations apply. An extended preheat time between +170C and +180C for 60 to 90s and a pin reflow temperature (TPIN) between +220C and +225C for 30 to 60 s is recommended. The extended preheat and soak at reflow temperature will minimize temperature gradients and maximize the wetting and solder mixing in the final solder joints. The use of nitrogen reflow atmosphere will further improve the solder joint quality. Temperature Solder bump Profile 60-90 s 170C to 180C 30-60 s 221C to 225C Time Dry Pack Information Products intended for Pb-free reflow 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). The SnPb option of this product is also delivered in dry packing. Reflow process specifications1 SnPb eutectic Average ramp-up rate 3C/s max 3C/s max +183C +221C Using products in high temperature Pb-free soldering processes requires dry pack storage and handling.

Automatic pick and place equipment should be used to mount the product on the host board. The use of a vision system, utilizing the fiducials on the bottom side of the product, will ensure adequate accuracy. Manual mounting of solder bump products is not recommended. A maximum pin temperature of +225C should be sufficient for most applications but depending on type of solder paste and flux system used on the host board, up to a recommended maximum temperature of +245C could be used, provided that the products are kept in a controlled environment (dry pack handling and storage) prior to assembly. Note that the actual position of the pick up surface may vary between variants within the product program and is not necessarily in the center of the product outline. Pb-free Solder Processes Repair For Pb-free solder processes, a pin temperature (TPIN) in excess of the solder melting temperature (TL, +217 to +221 C for SnAgCu 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. For a successful repair (removal and replacement) of a solder bump product, a dedicated rework system should be used. The rework system should preferably utilize a bottom side heater and a dedicated hot air nozzle to heat the solder bumps to reflow temperature. Maximum Product Temperature Requirements Top of the product PCB near pin 9 or 10 are chosen as reference locations for the maximum (peak) allowed product temperature (TPRODUCT), since these will likely be the warmest parts of the product during the reflow process. The product is an open frame design with a pick up surface on a large central component. This pick up surface can not be used for removal with a vacuum nozzle since the component solder joints may have melted during the removal reflow. SnPb Solder Processes For conventional SnPb solder processes, the product is qualified for MSL 1 according to IPC/JEDEC standard J-STD-020C (no dry pack handling or controlled environment required) During reflow, TPRODUCT must not exceed +225 C at any time. If the products are handled as MSL 3 products, they can withstand up to +260C as in Pb-free solder processes. Pb-free Solder Processes For Pb-free solder processes, the product is qualified for MSL 3 according to IPC/JEDEC standard J-STD-020C. The solder bumps of the product require particular care during assembly since the solder bumps are hidden between the host board and the product's PCB. Special procedures are required for successful rework of these products. If necessary, it is recommended to fine tune the solder print aperture size to optimize the amount of deposited solder with consideration to screen thickness and solder print capability. In order not to damage the product and nearby components during removal and replacement with a new product, it is recommended to use a double wall design of the hot air nozzle to direct the air flow only to the edges of the product, see `Assembly Information' in the mechanical drawing. Soldering Information -- Hole Mounting The hole mount version of the product is intended for manual or wave soldering in plated through holes on the host board. When wave soldering is used, the temperature on the pins is specified to maximum +270 C for maximum 10 seconds. A maximum preheat rate of 4C/s and a preheat 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 seconds in order to prevent overheating. During reflow, TPRODUCT must not exceed +260 C at any time. 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. Ericsson Internal PROD.
