This power module is negative logic version. When the REM pin is at logic high the power turns off and turns on at logic low. To turn the power module on and off, the user must supply a switch to control the voltage between the REM pin and -Vin terminal (see Figure 3). A logic low is VREM = -0.7V to 0.8V. The maximum IREM during logic low is 1mA. The switch should maintain a logic low voltage while sinking 1mA. During logic high, the typical maximum VREM voltage is18V. If not using the remote on/off feature, short REM pin to -Vin. Measure input reflected ripple current with a simulated source inductance of 12µH. The measurement points for input reflected ripple current is showed above. Scope measurements should be made using a BNC socket, with a 1µF ceramic capacitor and a 10 µF tantalum capacitor. Position the oscilloscope probe between 51mm and 76mm (2 inch and 3 inch) from the module. Input Reflected Ripple Current Test Setup Output Ripple and Noise Test Setup 3.3V 12V

This is accomplished by connecting an external resistor between the TRIM pin and either the Vout+ or Vout- pins. If not using the trim feature, leave the TRIM pin open.
