AE PIN LENGTH, example: PKM4304BPIPHSGLPLA Reliability The Mean Time Between Failure (MTBF) is calculated at full output power and an operating ambient temperature (TA) of +40C. Different methods could be used to calculate the predicted MTBF and failure rate which may give different results. Ericsson Power Modules currently uses two different methods, Ericsson failure rate data system DependTool and Telcordia SR332. Predicted MTBF for the series is: 1.1 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. 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. 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) EFEIDEN Approved PKM4000B PI SEC/D (Julia You) Checked 1/1301-BMR 653Technical Uen Specification Date 2008-7-21 Intermediate Bus Converters, Input 36-75 V, 33A/380W 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: * * * * * * 3 (4) No. 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. EC61204-7 "Safety standard for power supplies", 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. PKM-B has the following stand-off (see mechanical drawing for further information): - 0.7 mm stand-off to tallest insulated part (signal transformer's plastic housing) - 0.7 mm stand-off to tallest unconnected (floating) conductive part (the integrated transformer's and output inductor's ferrite cores) - 0.95 mm stand-off to tallest connected conductive part (input- and output capacitors) 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. Rev 3 Reference EN/LZT 146 305 R5A July 2008 G (c) Ericsson Power Modules AB 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 100 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.

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 115C. The absolute maximum continuous input voltage is 80 Vdc. 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.For loosely regulated DC/DC converters, such as PKM-B intermediate bus converters, there is no limit on the value of output capacitance that may be used. The user should be aware, however, that large values of capacitance will affect the ramp-up time of the DC/DC converter output voltage during start-up. Turn-off Input Voltage Parallel Operation 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. The PKM 4000B Series DC/DC converters can be connected in parallel with a common input. Paralleling is accomplished by connecting the output voltage pins and input pins directly. No external components are necessary. Up to 90% of max output current can be used from each module. Layout considerations should be made to avoid unbalanced current sharing. For more details on paralleling, please consult your local Ericsson Power Modules representative. Input Voltage Remote Control (RC) The products are fitted with a remote control function referenced to the primary negative input connection (- In), and positive logic options available. The RC function allows the DC/DC 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 0.2 mA. When the RC pin is left open, the voltage generated on the RC pin is max 10 V. 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 DC/DC converter will turn on when the RC pin is left 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 DC/DC converter will restart automatically when this connection is opened. 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 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 330 F capacitor across the input of the DC/DC converter will ensure stable operation. 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, Input Voltage 53V 12.0 Output Voltage (V) Operating information module 1 module 2 module 1 + 2 11.8 11.6 11.4 11.2 0 10 20 30 40 Output Current (A) 50 60 Ericsson Internal PRODUCT SPECIFICATION E Prepared (also subject responsible if other) ECHWANG Approved 3 (6) No. Checked 3/1301-BMR 653Technical Uen Specification Date PKM4000B PI EXUEFYA 2008-06-30 Intermediate Bus Converters, Input 36-75 V, 33A/380W Over Temperature Protection (OTP) The DC/DC converters are protected from thermal overload by an internal over temperature shutdown circuit. When Tref as defined in thermal consideration section exceeds 125C the DC/DC converter will shut down. The DC/DC converter will make continuous attempts to start up (non latching mode) We provide an optional variant of the product with a latching OTP. Add suffix "LP" to the standard product code to order the latching version. The latching OTP version has a latching OVP as well. If the OTP/OVP is latched the module can be put in operation either by switching OFF and ON the input voltage or drive OFF and ON the RC (Remote Control) pin. Over Voltage Protection (OVP) The DC/DC converters have output over voltage protection that will shut down the DC/DC converter in over voltage conditions. The DC/DC converter will make continuous attempts to start up (non-latching mode) and resume normal operation automatically after removal of the over voltage condition. Add suffix "LP" to the standard product code to order the latching version. The latching OVP version has a latching OTP as well. If the OTP/OVP is latched the module can be put in operation either by switching OFF and ON the input voltage or drive OFF and ON the RC (Remote Control) pin. Over Current Protection (OCP) The DC/DC converters include current limiting circuitry for protection at continuous overload. The output voltage will decrease towards zero when the output current exceeds max output current (max Io). Under output short circuit, when the output current is in excess of max output current (max Io), the DC/DC Converter will enter a hiccup mode protection. The DC/DC converter will resume normal operation after removal of the overload or short circuit.

Cooling is achieved mainly by conduction, from the pins to the host board, and convection. The size and copper thickness of the host board will have impact on the Conduction cooling. Convection cooling is dependant on the airflow across the DC/DC converter. Increased airflow enhances the cooling of the DC/DC 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. The DC/DC converter 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 305 x 305 mm. Proper cooling of the DC/DC converter can be verified by measuring the temperature at reference point. The temperature at these positions should not exceed the max values provided in the table below. Position Device Designation max value Reference PCB - 125C 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 reliability of the module. Ambient Temperature Calculation By using the thermal resistance the estimated 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 96 % = 0.96 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. Max allowed ambient temperature is: Ta=Max Tref - T. E.g. PKM4204B PI at 53Vin 20Aout 1.5 m/s 1. ((1/0.96) -- 1) x 240W = 10 W 2. 10 W x 3.5o C = 35o C 3. 125o C -- 35o C = max ambient temperature is 90o C The actual temperature will be dependent on several factors such as the PCB size, number of layers and direction of airflow.
