Stress in excess of Absolute Maximum Ratings may cause permanent damage. Absolute Maximum Ratings, sometimes referred to as no destruction limits, are normally tested with one parameter at a time exceeding the limits of Output data or Electrical Characteristics. If exposed to stress above these limits, function and performance may degrade in an unspecified manner.

Thermal Data
Two-parameter model
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.
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 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.
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.

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. SEMKO certificate no. 9738248. 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 case temperature to comply with TCmax 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. The isolation is an operational insulation in accordance with EN 60 950. The DC/DC power module is intended to be supplied by isolated secondary circuitry and shall be installed in compliance with the requirements of the ultimate application. One pole of the input and one pole of the output is to be grounded or both are to be kept floating. The terminal pins are only intended for connection to mating connectors of internal wiring inside the end-use equipment. These DC/DC power modules may be used in telephone equipment in accordance with paragraph 34 A.1 of UL 1459 (Standard for Telephone Equipment, second edition). The galvanic isolation is verified in an electric strength test. Test voltage (VISO) between input and output is 1,500 Vdc for 60 s. In production the test duration is decreased to 1 s. The capacitor between input and output has a value of 1 nF and the leakage current is less than 1A @ 26 Vdc. The case is designed in non-conductive epoxy. Its flamma-bility rating meets UL 94V-0. The oxygen index is 34%.

Operating Information
Fuse Considerations
To prevent excessive current from flowing through the input supply line, in the case of a short-circuit across the converter input, an external fuse should be installed in the non-earthed input supply line. 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).

Over Voltage Protection (OVP)
The remote control can be utilized also for OVP by using the external circuitry in figure 2. 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

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.

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.
Delivery Package Information
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.

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. 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.
Tape & Reel
SMD versions, SI, can be delivered in standard tape & reel package (designated by /C) on request, see fig. 7. For more information, please contact your local Ericsson sales office.
