Utilization of thick film technology and a high degree of silicon integration has made it possible to achieve a MTBF of more than 4.9 million hours. The high reliability and the very low height of these DC/DC power modules makes them particularly suited for Information Technology and Telecom (IT&T) applications, with board spacing down to 15 mm or 0.6 in. The over-moulded rugged design makes them also suitable for other demanding industrial applications. They are optimized for free convection cooling and have an operational ambient temperature range in compliance with present and future application needs, including non temperature controlled environments. The mechanical design offers the choice of surface mount or through-hole versions, delivered in ready-to-use tubes, trays or tape & reel package and compatibility with semi and fully aqueous cleaning processes. The PKF series is manufactured using highly automated manufacturing lines with a world-class quality commitment and a five-year warranty.

Thermally the power module can be considered as a component and the case temperature can be used to characterize the properties. The thermal data for a power module with the substrate in contact with the case can be described with two thermal resistances. One from case to ambient air and one from case to PB (Printed circuit Board). The thermal characteristics temperature can be calculated from the following formula: TPB = (TC–TA)×(Rth C–PB+Rth C–A)/Rth C–A–Pd×Rth C–PB+TA Where: dissipated power, calculated as PO ×(l/h –1) max average case temperature ambient air temperature at the lower side of the power module temperature in the PB between the PKF connection pins TPB: Rth C-PB: thermal resistance from case to PB under the power module Rth C-A: thermal resistance from case to ambient air v: velocity of ambient air Rth C-PB is constant and Rth C-A is dependent on the air velocity. Pd: TC: TA: Free convection is equal to an air velocity of approx. 0.2 – 0.3 m/s. See figure below. Reflow Soldering Information The PKF series of DC/DC power modules are manufactured in surface mount technology. Extra precautions must therefore be taken when reflow soldering the surface mount version. Neglecting the soldering information given below may result in permanent damage or significant degradation of power module performance. The PKF series can be reflow soldered using IR, Natural Convection, Forced Convection or Combined IR/Convection Technologies. The high thermal mass of the component and its effect on DT (°C) requires that particular attention be paid to other temperature sensitive components. IR Reflow technology may require the overall profile time to be extended to approximately 8–10 minutes to ensure an acceptable DT. Higher activity flux may be more suitable to overcome the increase in oxidation and to avoid flux burn-up. The general profile parameters detailed in the diagram, with this extended time to reach peak temperatures, would then be suitable. Note! These are maximum parameters. Depending on process variations, an appropriate margin must be added. Palladium plating is used on the terminal pins. A pin temperature (Tp) in excess of the solder fusing temperature (+183°C for Sn/Pb 63/37) for more than 25 seconds and a peak temperature above 195°C, is required to guarantee a reliable solder joint. Both pin 1 and pin 9 must be monitored. No responsibility is assumed if these recommendations are not strictly followed. 4 EN/LZT 146 33 R1A (Replaces EN/LZT 137 09 R7) © Ericsson Microelectronics AB, June 2000 Safety The PKF Series DC/DC power modules are designed in accordance with EN 60 950, Safety of information technology equipment including electrical business equipment. SEMKO certificate no. 9709166. The PKF power modules are recognized by UL and meet the applicable requirements in UL 1950 Safety of information technology equipment, the applicable Canadian safety requirements and UL 1012 Standard for power supplies. The DC/DC power module shall be installed in an end-use equipment and considerations should be given to measuring the pin temperature to comply with TPmax when in operation. Abnormal component tests are conducted with the input protected by an external 3 A fuse. The need for repeating these tests in the end-use appliance shall be considered if installed in a circuit having higher rated devices. When the supply to the DC/DC power module meets all the requirements for SELV (37 V): RIon = 100× (100.2 – VIon)/(VIon – 36.5) kW where 36.5 is the typical unadjusted turn-on input voltage (V). VIoff is the adjusted turn-off input voltage and is determined by VIon –VIoff = 2 V (typical value). To decrease VIon a resistor should be connected between pin 10 and 11 (see fig. 3). The resistance is given by the following equation (for 30 V < VIon > 36 V: RIon = 364 × (VIon – 29.9)/(36.5 – VIon) kW Remote Control (RC) Turn-on or turn-off can be realized by using the RC-pin. Normal operation is achieved if pin 11 is open (NC). If pin 11 is connected to pin 17 the power module turns off. To ensure safe turn-off the voltage difference between pin 11 and 17 shall be less than 1.0 V. RC is TTL open collector compatible output with a sink capacity >100 mA (see fig. 1).

Typical adjust range is ± 15%. If pins 8 and 9 are not connected together the output will decrease to a low value. To increase VO a resistor should be connected between pin 8/9 and 18, and to decrease VO a resistor should be connected between pin 8 and 9 (see fig. 4). Typical required resistor value to increase VO is given by: Radj = k1 × (k2 – VO)/(VO – VOi) kW where VO is the desired output voltage, VOi is the typical output voltage initial setting k1=0.684 k1=0.495 k1=0.495 k1=0.566 k1=0.495 k1=0.495 k1=0.495 k1=0.566 k2= 2.46 V k2= 3.93 V k2= 5.87 V k2=15.00 V k2= 5.87V k2= 3.93 V k2= 5.87 V k2=15.00 V PKF 4310 PKF 4510 PKF 4611 PKF 4621*) PKF 4622 PKF 4628 PKF 4629 PKF 4713*) Figure 1 Over Voltage Protection (OVP) The remote control can be utilized also for OVP by using the external circuitry in figure 2.

Their equivalent series resistance together with the capacitance acts as a lossless damping filter. Suitable capacitor values are in the range of 10–100 mF. Tantalum capacitors are not recommended due to their low ESRvalue.

Voltage Margin For voltage controlled margining e.g. at final test, the following setup can be used. By increasing the control voltage V1 to +10 V the output voltage decreases 5% of VOi, and by decreasing V1 to –10 V the output voltage increases 5%. Figure 6 Specification Figure 5 Capacitive Load The PKF series has no maximum limit for capacitive load on the output. The power module may operate in current limiting mode during start-up, affecting the ramp-up and the start-up time. For optimum start performance we recommend maximum 100 mF/A of IO. Connect capacitors at the point of load for best performance.

For more information, please contact your local Ericsson sales office. Parallel Operation Paralleling of several converters is easily accomplished by direct connection of the output voltage terminal pins. 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 × 0.9 × POmax, where POmax is the maximum converter output power and n the number of paralleled converters, to prevent overloading any of the converters and thereby decreasing the reliability performance. Current Limiting Protection (Ilim) The output power is limited at loads above the output current limiting threshold (Ilim), specified as a minimum value. Input and Output Impedance Both the source impedance of the power feeding and the load impedance will interact with the impedance of the DC/DC power module. It is most important to have the ratio between L and C as low as possible, i.e. a low characteristic impedance, both at the input and output, as the power modules have a low energy storage capability. 20 Figure 7 EN/LZT 146 33 R1A (Replaces EN/LZT 137 09 R7) © Ericsson Microelectronics AB, June 2000 Specification Quality Polypropylene (PP) 125 ºC 105W/ Black 15 power modules/tray 10.16 mm Typ. 130 g 150 pcs (one box contains 10 full trays) Material: Max temperature: Max surface resistance: Color: Capacity: Stacking pitch: Weight: Min. order quantity: Reliability Meantime between failure (MTBF) is calculated to >4.9 million hours at full output power and a pin temperature of +50 °C (TA = +40 °C), using the Ericsson failure rate data system.
