46–60 W DC/DC Power Modules

24 V Input Series

• Efficiency typ 84% at 5 V and full load  Low profile 11.0 mm (0.43 in.)  1 ,500 V dc isolation voltage (duals = 1,000 Vdc )  MTBF > 200 years at +75 °C case temperature  Rugged mechanical design and efficient thermal management, max +100 °C case temperature  EMI measured according to EN 55 022 and FCC part 15J The PKG 2000 I series of low profile DC/DC Power Modules are intended as distributed power sources in decentralized +24 V DC power systems. They can be used as on-board distributed power modules, or serve as building blocks for more centralized power boards. The PKG series of DC/DC power modules provide up to 60W of output power utilizing the standard EriPower™ PKA/PKE pin-out, with an even smaller footprint, and a power density of 20 W/cu.in. The high efficiency makes it possible to operate over a wide temperature range without any extra heat- sinks. At forced convection cooling >200 lfm (1 m/s), the PKG units can deliver full power without heatsinks up to +60°C ambient. With derated output power it can also operate in temperature controlled environments with free convection cooling. By adding external heatsinking, the temperature range can be extended even further. Thanks to their peak power capability, the PKG series is ideal for applications where max power is only required during short durations e.g. in disc drives. The PKG series use ceramic substrates with plated copper in order to achieve good thermal management, low voltage drops and a high efficiency. These products are manufactured using highly automated manufacturing lines with a world-class quality commitment and a five-year warranty.

The PKG 2000 I Series DC/DC power mod- ules are designed in accordance with EN 60 950, Safety of information technology equipment including electrical business equipment and certi- fied by SEMKO. The PKG power modules are recognized by UL and meet the applicable requirements in UL 1950 Safety of information technology equip- ment, the applicable Canadian safety require- ments and UL 1012 Standard for power sup- plies. The DC/DC power module shall be installed in an end-use equipment and considerations should be given to measuring the case tem- perature to comply with TCmax when in operation. They are intended to be supplied by isolated secondary circuitry and shall be installed in compliance with the require- ments of the ultimate application. If connect- ed to a 24 V DC power system reinforced insulation must be provided in the power supply that isolates the input from the ac mains. The isolation in the DC/DC power module is an operational insulation in accord- ance with EN 60 950. 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. The isolation voltage is a galvanic isolation and is verified in an electric strength test. Test voltage (V ISO) between input and output and between case and output is 1,500 Vdc (duals = 1,000Vdc) for 60 s. In production the test duration may be de- creased to 1 s. The capacitor between input and output has a value of 4.7 nF (duals = 22 nF) and the leak- age current is less than 1 /G109A @ 26Vdc. Flammability ratings of the terminal support and internal plastic construction details meets UL 94V-0. Absolute Maximum Ratings 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.

Power dissipation is generated in the components mounted on the ceramic substrate. The thermal properties of the PKG DC/DC power module is determined by thermal conduction in the connected pins and thermal convection from the substrate via the case. The two-parameter model characterize the thermal properties of the PKG power module and the equation below can be used for thermal design purposes if detailed information is needed. The values are given for a power module mounted on a printed board assembly (PBA). Note that the thermal resistance between the substrate and the air, Rth sub-A is strongly dependent on the air velocity. Tsub = Pd × Rth sub-P × Rth sub-A/(Rth sub-P + Rth sub-A) + (TP–TA) × Rth sub-A/(Rth sub-P + Rth sub-A) + TA Where: Pd : dissipated power, calculated as PO × (1//G104-1) Tsub : max average substrate temperature, /G187 TC max TA : ambient air temperature at the lower side of the power module TP : average pin temperature at the PB solder joint Rth sub-P : thermal resistance from Tsub to the pins Rth sub-A : thermal resistance from Tsub to TA v : velocity of ambient air. Air velocity in free convection is 0.2–0.3 m/s (40-60 lfm). Over Temperature Protection (OTP) The PKG DC/DC power modules have an internal over temperature protection circuit. If the case temperature exceeds min +115°C the power module will go in to OTP-mode. As long as the case tempera- ture exceeds min +115°C the power module will operate in OTP- mode. During OTP-mode the output voltage pulsates between zero and nominal output voltage, which reduces the power loss inside the power module. The PKG DC/DC power module will automatically resume normal operation when the temperature decreases below min +115°C.

Current Limiting Protection The output power is limited at loads above the output current limit- ing threshold (Ilim), specified as a minimum value. Turn-on/off Input Voltage (TOA) The power module monitors the input voltage and will turn on and turn off at predetermined levels. The levels can be decreased by means of an external resistor connected between pin 2 and pin 4. A 0.2 M /G87 resistor will decrease the turn-off input voltage approxi- mately 10%. Input and Output Impedance Both the source impedance of the power feeding and the load imped- ance 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 possi- ble, 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 or output if the source or load inductance is larger than 10 /G109H. Their equivalent series resistance together with the capacitance acts as a lossless damping filter. Suitable capacitor values are in the range 10–100 /G109F. Parallel Operation The load regulation characteristic and temperature coefficient of the PKG DC/DC Power Modules are designed to allow parallel operation. Paralleling of several modules is easily accomplished by connection of the output voltage terminal pins. The connections should be symmet- rical, i.e. the resistance between the output terminal and the common connection point of each module should be equal. Good paralleling performance is achieved if you allow the resistance to be 10 m /G87. 10 m/G87 equals 50 mm (2 in) of 35 /G109m (1 oz/ft2) copper with a trace width of 2.5 mm (0.1 in). It is recommended not to exceed PO =n × 0.8 × POmax, where POmax is the maximum power module output power and n the number of paralleled units, not to overload any of them and thereby decrease the reliability performance. Paralleling performance may be further improved by voltage match- ing. Voltage matching is accomplished by using the Output Adjust function and trim the outputs to the same voltage. Output Voltage Adjust (Vadj) The utput voltage, VO, can be adjusted by using an external resistor. A 0.1 M/G87 resistor will change VO approximately 5%. To decrease the output voltage the resistor should be connected between pin 10 and pin 9 (+Out 1). To increase the output voltage the resistor should be connected between pin 10 and pin 8 (–Out 1). Maximum Capacitive Load The PKG series has no limitation of maximum connected capacitance 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 performance we recommend maximum 100 /G109F/A of IO for dual outputs. Connect capacitors at the point of load for best per- formance. RC (pin 1) PKG TTL /c45In (pin 3) Fig. 1 Remote Control (RC) Remote turn-on and turn-off can be realized by using the RC-pin. Normal operation is achieved if pin 1 is open (NC). If pin 1 is con- nected to pin 3 the PKG power module turns off. To ensure safe turn- off the voltage difference between pin 1 and 3 shall be less than 1.0 V. RC is TTL open collector compatible (see fig. 1). Over Voltage Protection (OVP) The PKG series has an internal Over Voltage Protection circuitry. The circuitry will detect over voltage conditions on the output and stop the power module operation. During OVP conditions there are contin- uous attempts to start up (non-latching mode). If latching mode is preferred an external circuit can be used to change the function and make the output remain in off mode after over voltage detection. (The OVP level can be found in the output data section.) RC (pin 1) /c45V (pin 3)I Reset /c43V (pin 4)I 6.8k 10k 10k

13EN/LZT 146 03 R1A (Replaces EN/LZT 137 R5) ©Ericsson Microelectronics AB, April 2000 Quality Statement The products are designed and manufactured in an industrial environ- ment where quality systems and methods like ISO 9000, 6/G115 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. Reliability Meantime between failure (MTBF) is calculated to >1.7 million hours at full output power and a case temperature of +75°C (TA =+40°C), 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 correspond to actual failure rates of component used in Infor- mation Technology and Telecom equipment in temperature controlled environments (T A =–5…+65°C).
