REMOTE ON/OFF APPLICATION CIRCUITS

Positive Logic

The positive logic structure turns the DC/DC module ON during a logic High on the CTRL pin and turns the DC/DC module OFF during a logic low

on the CTRL pin. The CTRL pin is an open collector/drain logic input signal (Von/off) that is referenced to GND. When not using the remote

ON/OFF feature please open circuit between the CTRL pin and input pin to turn the module ON.
