Figure 2 gives several examples of acceptable configurations. The remote ON/OFF pin is an open collector/drain logic input signal (Von/off) that has –Vin as the reference voltage. If not using the remote on/off feature, open the circuit between the on/off pin and the –input pin to turn the module on.

This is accomplished by connecting an external resistor between the TRIM pin and either the +Vout or -Vout pins. With an external resistor between the TRIM and -Vout pin, the output voltage set point increases. With an external resistor between the TRIM and +Vout pin, the output voltage set point decreases.
