Remote ON/OFF Control
The Remote ON/OFF Pin is used to turn on and off the DC/DC power module. The
user must use a switch to
control the logic voltage (high or low level ) of the pin referenced to -Vin. The switch can be anopen col
lector transistor,
FET and Opto-Coupler. The switch must be capable of sinking up to 0.5 mA at low-level logic voltage. High-
level logic
of the ON/OFF signal (maximumvoltage):the allowable leakage current ofthe switch at 12V is 0.5mA.
