Remote ON/OFF Control
The Remote ON/OFF Pin is controlled DC/DC power module to turn on and off; the user must use a switch to
control the logic voltage high or low level of the pin referenced to Vi (-). The switch can be open collector
transistor, FET and Photo-Couple. The switch must be capable of sinking up to 1mA at low-level logic Voltage.
High-level logic of the ON/OFF signal maximum voltage is allowable leakage current of the switch at 15V is
50uA.

There are two remote control options available, positive logic and negative logic.
a. The Positive logic structure turned on the DC/DC module when the ON/OFF pin is at high-level logic
and low-level logic is turned off it.

b. The Negative logic structure turned on the DC/DC module when the ON/OFF pin is at low-level logic
and turned off when at high-level logic.
