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 ex-tended time to reach peak temperatures, would then be suitable. Note! These are maximum parameters. Depending on process variations, an appropriate margin must be added. This model provides a more precise description of the thermal characteristics to be used for thermal calculations. 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 the case to ambient air and one from case to PB (Printed Board). The thermal characteristics can be calculated from the following formula: TPB = (TC-TA)x(Rth C-PB+Rth C-A)/Rth C-A-PdxRth C-PB+TA Where: P d: dissipated power, calculated as PO x(l/h-1) max average case temperature TC: TA: ambient air temperature at the lower side of the power module TPB: temperature in the PB between the PKF connection pins 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. Free convection is equal to an air velocity of approx. 0.2 - 0.3 m/s. See figure below. Palladium plating is used on the terminal pins. A pin tem-perature (Tp) in excess of the solder fusing temperature (+183C for Sn/Pb 63/37) for more than 25 seconds and a peak temperature above 195C, 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 31 R1B (c) Ericsson Power Modules AB, March 2004 Safety The PKF 2000 I series DC/DC power modules are designed in accordance with EN 60 950, Safety of information technology equipment including electrical business equipment.

We recommend using a fuse rated at approximately 2 to 4 times the value calculated in the formula below: Iin max = PO max (hmin x VI min) Refer to the fuse manufacturer for further information. 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 18 the power module turns off. To ensure safe turnoff the voltage difference between pin 11 and 18 shall be less than 1.0V. RC is an TTL open collector compatible output with a sink capacity >300 mA (see fig. 1). To increase VIon a resistor should be connected between pin 11 and 18 (see fig. 3). The resistance is given by the following equation (For VIon>18.4V): RIon = (k1 - VIon)/(VIon - k2) kW where k2 is the typical unadjusted turn-on input voltage (V). 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 17.0V < VIon >18.3V: RIon = k3 x (VIon - k4)/(k2 - VIon) kW k1 k2 k3 k4 1020 18.3 22 16.9 PKF 2111A, PKF 2113A 1020 18.4 27 17.0 PKF 2610A 1020 18.4 25 17.0 PKF 2611 Turn-off level. VIoff is the adjusted turn-off level and is determined by the following equation: VIoff = VIon - 1.5V (typical value).

Resistor values are for 5V output applications, but can easily be adjusted for other output voltages and the desired OVP level. Out 1 (pin 1) 15k 1.2k 1k TL431 10k 270 RC (pin 11) Output voltage, VO, can be adjusted by using an external resistor. Typical adjust range is 15%. If pin 8 and 9 is 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 = k5 x (k6 - VO)/(VO - VOi) kW where VO is the desired output voltage, VOi is the typical output voltage initial setting and k5= 4.2 k6= 6.27 V PKF 2111A k6= 15.0 V PKF 2113A k5= 4.2 k5= 3.18 k6= 3.90V PKF 2610A k6= 5.85V PKF 2611 k5= 3.18 Typical required resistor value to decrease VO is given by: Radj = k7 x (VOi - VO)/(VO - k8) kW where Rtn (pin 2) In (pin 18) k7= 18.0 k7= 18.6 k7= 17.2 k7= 12.5 k8= 2.76 V k8= 6.50 V k8= 1.70 V k8= 4.28 V PKF 2111A PKF 2113A PKF 2610A PKF 2611 Figure 2 Increase VO Decrease VO -In (pin 18) Vadj (pin 8) Turn-on/off Input Voltage The power module monitors the input voltage and will turn on and off at predetermined levels. The typical turn-on level (without any external resistor) is 18.4 V and the typical turn-off level is 17.0 V, a slight deviation can occur due to tolerances in the manufacturing process. These levels can be adjusted by means of external resistors.

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. Tubes The PKF-series is delivered in tubes (designated by /A) with a length of 500 mm (19.69 in), see fig. 5. 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 x 0.9 x 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.

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. Use an electrolytic capacitor across the input if the source inductance is larger than 10 mH. Their equivalent series resistance together with the capacitance acts as a lossless damping filter. Suitable capacitor values are in the range 10-100 mF.

Quality Reliability Meantime between failure (MTBF) is calculated to >4.9 million hours at full output power and a pin temperature of +50C (TA = +40C), using the Ericsson failure rate data system. The Ericsson failure rate data system is based on field failure rates and is continously updated. The data corresponds to actual failure rates of components used in Information Technology and Telecom equipment in temperature controlled environments (TA = -5... +65C). The data is considered to have a confidence level of 90%. For more information see Design Note 002. Quality Statement The products are designed and manufactured in an industrial environment where quality systems and methods like ISO 9000, 6s and SPC, are intensively in use to boost the continuous improvements strategy. Infant mortality or early failures in the products are screened out by a burn-in procedure and 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.
