The parts count procedure used in this method was originally modelled on the methods from MIL-HDBK217F, 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.

General Information 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 Telcordia SR332. Predicted MTBF for the series is: 1.67 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 ICT equipment in temperature controlled environments (TA = -5...+65C). 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) 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.

Safety Specification Isolated DC/DC converters General information 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: 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 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 * * 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.

Conducted EMI Input terminal value (typ) Test set-up Layout recommendations The radiated EMI performance of the Product will depend on the PCB layout and ground layer design. It is also important to consider the stand-off of the product. If a ground layer is used, it should be connected to the output of the product and the equipment ground or chassis.

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 +110C. The absolute maximum continuous input voltage is 80 Vdc. Turn-off Input Voltage The products 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 product 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 5.0 - 7.0 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 1V. To turn off the converter the RC pin should be left open, or connected to a voltage higher than 13 V referenced to -In. 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 second option is "positive logic" remote control, which can be ordered by adding the suffix "P" to the end of the part number. When the RC pin is left open, the product starts up automatically when the input voltage is applied. 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 product 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 product. It is important that the input source has low characteristic impedance. The products are designed for stable operation without external capacitors connected to the input or output. The performance Rev Reference 22 EN/LZT 146 416 R3A February 2010 E (c) Ericsson AB 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 22 - 100 F capacitor across the input of the product will ensure stable operation. The capacitor is not required when powering the product from an input source with an inductance below 10 H. The minimum required capacitance value depends on the output power and the input voltage. The higher output power the higher input capacitance is needed. Approximately doubled capacitance value is required for a 24 V input voltage source compared to a 48V input voltage source. 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. It is equally important to use low resistance and low inductance PCB layouts and cabling. 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 >5 m across the output connections. For further information please contact your local Ericsson Power Modules representative. Output Voltage Adjust (Vadj) The products 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 product from shutting down. At increased output voltages the maximum power rating of the product 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 load distribution system should be designed to carry the maximum output short circuit current specified. The PKMD series include hiccup OCP option, the output voltage will decrease when the output current in excess of its current limit point, when the load continue to increase to some higher level, the module will enter into hiccup mode. During hiccup, the module will try to restart and shutdown again for the overload. When the overload is removed, the products will continue to work normally. Thermal Consideration Parallel Operation Two products may be paralleled for redundancy if the total power is equal or less than PO max. It is not recommended to parallel the products without using external current sharing circuits. See Design Note 006 for detailed information. 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 output pins and the point of load. General The products are designed to operate in different thermal environments and sufficient cooling must be provided to ensure reliable operation. For products mounted on a PCB 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), 16-layer test board mounted vertically in a wind tunnel with a cross-section of 608 x 203 mm. 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 products are protected from thermal overload by an internal over temperature shutdown circuit. When TP1 as defined in thermal consideration section exceeds 135C 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 >15C below the temperature threshold. Over Voltage Protection (OVP) The products have output over voltage protection that will shut down the product in over voltage conditions. The product will make continuous attempts to start up (non-latching mode) and resume normal operation automatically after removal of the over voltage condition. Over Current Protection (OCP) The products include current limiting circuitry for protection at continuous overload. PKMD standard module, the output voltage will decrease towards zero for output currents in excess of max output current (Iomax). The converter will resume normal operation after removal of For products with base plate used in a sealed box/cold wall application, cooling is achieved mainly by conduction through the cold wall. The Output Current Derating graphs are found in the Output section for each module. The product is tested in a sealed box test set up with ambient temperatures 85 and 35C. See Design Note 028 for further details.

The temperature at these positions TP1, TP2 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 Temp. P1 MOSFET TP1=125 C P2 Control IC TP2=125 C 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. 89.5% = 0.895 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. E.g. PKM 4111D PINBat 1.5m/s: 1. (( P1 1 ) - 1) x 125 W = 12.4W 0.91 2. 12.4 W x 3.5C/W = 43.4C P2 3. 125 C - 43.4C = max ambient temperature is 81.6C The actual temperature will be dependent on several factors such as the PCB size, number of layers and direction of airflow.
