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 uses two different methods, Ericsson failure rate data system DependTool and Telcordia SR332. Predicted MTBF for the series is: 2.7 million hours according to DependTool. 1.4 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). 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) 2 Reference EN/LZT 146 307 R4B August 2009 F (c) Ericsson Power Modules AB - See Contents for individual product ordering numbers.

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.

Baseplate helps to cool hotspots more efficient during heavy load. The baseplate have approximately 5C improved derating compared to datasheet showing non baseplated PKM4000C. The baseplate is intended to be mounted on a cold wall to transfer heat away from the converter. By mounting PKM4000C in this way thermal derating can be improved by more than 10C.

The fundamental switching frequency is 200 kHz for PKM 4211C PINB @ VI = 53 V, max IO. Conducted EMI Input terminal value (typ) Test set-up Layout recommendation The radiated EMI performance of the DC/DC converter will depend on the PCB layout and ground layer design. 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. EMI without filter External filter (class B) A ground layer will increase the stray capacitance in the PCB and improve the high frequency EMC performance. Required external input filter in order to meet class B in EN 55022, CISPR 22 and FCC part 15J. Output ripple and noise Output ripple and noise measured according to figure below. See Design Note 022 for detailed information.

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 80Vdc. Turn-off Input Voltage The PKM 4000CSeries 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. 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 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 power source and the load will interact with the impedance of the DC/DC converter. It is most important to have a low characteristic impedance, both at the input and output, as the converters have a low energy storage capability. The PKM 4000CSeries DC/DC converters have been designed to be completely stable without the need for external capacitors on the input or the output circuits. The performance in some applications can be enhanced by addition of external capacitance as described under maximum capacitive load. If the distribution of the input voltage source to the converter contains significant inductance, the addition of a 100F capacitor across the input of the converter will help insure stability. This capacitor 3/1301-BMR 637Technical 01 Uen Specification Date 2007-12-10 Rev 15 Reference EN/LZT 146 307 R4B August 2009 C (c) Ericsson Power Modules AB is not required when powering the DC/DC converter from a low impedance source with short, low inductance, input power leads. 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. 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) All PKM 4000CSeries 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 offset) must be kept below the maximum output adjust range. Also note that at increased output voltages the maximum power rating of the converter remains the same, and the output current capability will decrease correspondingly. To decrease the output voltage the resistor should be connected between Vadj pin and --Sense pin. To increase the voltage the resistor should be connected between Vadj pin and +Sense pin. The resistor value of the Output voltage adjust function is according to information given under the output section.

It is not recommended to parallel the PKM 4000C Series DC/DC converters for increased power without using external current sharing circuits. The PKM 4000Cseries DC/DC converters are designed to operate in a variety of thermal environments, however sufficient cooling should be provided to help ensure reliable operation. Heat is removed by conduction, convection and radiation to the surrounding environment. Increased airflow enhances the heat transfer via convection. The available load current vs. ambient air temperature and airflow at Vin =53 V for each model is according to the information given under the output section. The test is done in a wind tunnel with a cross section of 305 x 305 mm, the DC/DC converter vertically mounted on a 16 layer Pcb with a size of 254 x 254 mm, each layer with 35 m (1 oz) copper. Proper cooling can be verified by measuring the temperature of selected devices. Peak temperature can occur at positions P1 - P4. The temperature at these positions should not exceed the recommended max values. See Design Note 006 for detailed information. Remote Sense All PKM 4000CSeries DC/DC converters have remote sense that can be used to compensate for moderate amounts of resistance in the distribution system and allow for voltage regulation at the load or other selected point. The remote sense lines will carry very little current and do not need a large cross sectional area. However, the sense lines on the Pcb should be located close to a ground trace or ground plane. In a discrete wiring situation, the use of twisted pair wires or other technique to reduce noise susceptibility is highly recommended. The remote sense circuitry will compensate for up to 10% voltage drop between the sense voltage and the voltage at the output pins. The output voltage and the remote sense voltage offset must be less than the minimum over voltage trip point. If the remote sense is not needed the --Sense should be connected to --Out and +Sense should be connected to +Out. Over Temperature Protection (OTP) The PKM 4000CSeries DC/DC converters are protected from thermal overload by an internal over temperature shutdown circuit. When the Pcb temperature (TC reference point) exceeds the temperature trig point (~120 C) the OTP circuit will cut down output power. The converter will stop until safe operating temperature is restored. Hysteresis between OTP trig point and restart is approx 10C. Time between OTP and restart is dependant on cooling of DC/DC converter. Over Voltage Protection (OVP) The PKM 4000CSeries DC/DC converters have output overvoltage protection. In the event of an output overvoltage condition, the converter will shut down immediately. The converter make continous attempts to start up (non-latching mode) and resume normal operation automatically. Over Current Protection (OCP) The PKM 4000CSeries DC/DC converters include current limiting circuitry that allows them to withstand continuous overloads or short circuit conditions on the output. 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 the overload. The load distribution system should be designed to carry the maximum output short circuit current specified. Note that the max value is the absolute maximum rating (non destruction) and that the electrical Output data is guaranteed up to Tref +90C. See Design Note 019 for further information.

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 90 % = 0.90 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: Max Tref - T. E.g PKM 4213C PINBSP at 2m/s: 1. (( 1 ) - 1) x 204 W = 14.6 W 0.933 2. 14.6 W x 5.7C/W = 83C 3. 110 C -- 83C = max ambient temperature is 27C The real temperature will be dependent on several factors, like Pcb size and type, direction of airflow, air turbulence etc. It is recommended to verify the temperature by testing.
