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. Reliability Warranty 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. Warranty period and conditions are defined in Ericsson Power Modules General Terms and Conditions of Sale. Predicted MTBF for the series is: 1.46 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. 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) 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 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 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 the 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.

It is also important to consider the stand-off of the DC/DC converter. If a ground layer is used, it should be connected to the output of the DC/DC converter and the equipment ground or chassis. A ground layer will increase the stray capacitance in the PCB and improve the high frequency EMC performance. Output ripple and noise Output ripple and noise measured according to figure below.

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 +125C. The absolute maximum continuous input voltage is 80Vdc. 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 1V. 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 1 mA. When the RC pin is left open, the voltage generated on the RC pin is 3.5 -- 6.0 V. The maximum allowable leakage current of the switch is 50A . 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 1V. 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 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 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. 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. Power Modules guarantee stable operation with a verified ESR value of >10 m across the output connections. For further information please contact your local Ericsson Power Modules representative. Output Voltage Adjust (Vadj) The DC/DC 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. 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.

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. 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. 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. Proper cooling of the DC/DC converter can be verified by measuring the temperature at positions {P1 and P2}. The temperature at these positions should not exceed the max values provided in the table below. Note that the max value is the absolute maximum rating (non destruction) and that the electrical Output data is guaranteed up to Tref {+90}C. See Design Note 019 for further information. Position Device Designation max value Over Temperature Protection (OTP) P1 Pcb Tsurface 125 C The converters are protected from thermal overload by an internal over temperature shutdown circuit. When Tref P1 as defined in thermal consideration section exceeds 135C the converter will shut down immediately (latching). The DC/DC converter can be restarted by cycling the input voltage or using the remote control function. P2 Transformer Tcore 125 C Over Voltage Protection (OVP) The converters have latching output over voltage protection that immediately will shut down the converter in over voltage conditions. The DC/DC converter can be restarted by cycling the input voltage or using the remote control function. 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. Thermal Consideration General 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 host board, and convection, which is dependant on the airflow across the converter. Increased airflow enhances the Airflow E Ericsson Internal PRODUCT SPECIFICATION Prepared (also subject responsible if other) HF/MPM/BY/P Anders Wagmark Approved PKJ 4110E PI HF/MPM/BY/P (Anders Wagmark) 4 (5) No. Checked (MICHEBO) 3/1301-BMR623 Technical Specification Date Rev EN/LZT 146 383 R1A June 2007 2007-06-04 DC/DC converters, Input 36-75 V, Output up to 30 A/100 W Thermal Consideration continued Reference A (c) Ericsson Power Modules AB Connections The converters can be ordered with a heatsink (HS) option. The heatsink option have approximately 5C improved derating compared to without heatsink. The heatsink option is intended to be mounted on a cold wall or heatsink to transfer heat away from the converter and further improve the cooling of the converter. 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. 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 88.5 % = 0.885 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 3.
