Remote ON/OFF Control
The RemoteON/OFF Pin is used to turn the converter on and off.The usermust use a switch to control the logic
voltage (high or low level) of the pin referenced to Vi (-). The switch can be an open collector transistor, FET or
Opto-Coupler. The switch must be capable of sinking up to 0.5 mAat low-level logic voltage. Using High-levellogic,
the
maximum allowableleakage current of the switchat 12Vis 0.5 mA.

Level Control UsingLineVoltage
There are two remote control options available, positive logic and negative logic.
a. Positive logic:
Turned off atLow-level logic Tturned on at High-level logic
b. Negative logic:
