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.

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 below. The module outputs shall not be adversely affected (regulation and operation) when the Trim pin is left open.
