DS_IPM24S0A0_02262013 8 DESIGN CONSIDERATIONS Remote On/Off The IPM series power modules have an On/Off control pin for output voltage remote On/Off operation. The On/Off pin is an open collector/drain logic input signal that is referenced to ground. When On/Off control pin is not used, leave the pin unconnected. The remote on/off pin is internally connected to +5Vdc through an internal pull-up resistor. Figure 27 shows the circuit configuration for applying the remote on/off pin. The module will execute a soft start ON when the transistor Q1 is in the off state. The typical rise for this remote on/off pin at the output voltage of 2.5V and 5.0V are shown in Figure 17 and 18. Vo On/Off Vin GND IPM RL Figure 27: Remote on/off implementation FEATURES DESCRIPTIONS Over-Current Protection To provide protection in an output over load fault condition, the unit is equipped with internal over -current protection. When the over -current protection is triggered, the unit enters hiccup mode. The units operate normally once the fault condition is removed. Output Voltage Programming The output voltage shall be externally adjustable by use of a Trim pin. The module output shall be adjusted by either a voltage source referenced to ground or an external resistor be connected between trim pin and Vo or ground. To trim-down using an external resistor, connect a resistor between the Trim and Vo pin of the module. To trim-up using an external resistor, connect a resistor between the Trim and ground pin of the module. The value of resistor is defined as is defined below. The module outputs shall not be adversely affected (regulation and operation) when the Trim pin is left open. Trim up Rtrim = (Vout-0.7)*7.5 (KΩ ) Vadj-Vout Trim Down Rtrim = (Vadj-0.7)*5.36 - (KΩ ) Vout-Vadj Rtrim is the external resistor in KΩ Vadj is the desired output voltage Vout is the output voltage without trim resistor IPM can also be programmed by applying a voltage between the TRIM and GND pins (Figure 31). The following equation can be used to determine the value of Vtrim needed for a desired output voltage Vo:
DS_IPM24S0A0_02262013 10 THERMAL CONSIDERATIONS Thermal management is an important part of the system design. To ensure proper, reliable operation, sufficient cooling of the power module is needed over t he entire temperature range of the module. Convection cooling is usually the dominant mode of heat transfer. Hence, the choice of equipment to characterize the thermal performance of the power module is a wind tunnel. Thermal Testing Setup Delta’s DC/DC power modules are characterized in heated vertical wind tunnels that simulate the thermal environments encountered in most electronics equipment. This type of equipment commonly uses vertically mounted circuit cards in cabinet racks in which the power modules are mounted. The following figure shows the wind tunnel characterization setup. The power module is mounted on a test PWB and is vertically positioned within the wind tunnel. The height of this fan duct is constantly kept at 25.4mm (1’’). Thermal Derating Heat can be removed by increasing airflow over the module. To enhance system reliability, the power module should always be operated below the maximum operating temperature. If the temperature exceeds the maximum module temperature, reliability of the unit may be affected.
