Remote ON/OFF Control
The RemoteON/OFF Pinis used to turn on and off the DC/DC converter.The user mustuse a switch to control
thelogic voltage (highor low level) of the ON / OFF pin referenced toVi (-). The switch can be an open collector
transistor, FET orPhoto-Coupler thatis capable of sinkingup to 1 mAat low-level logic voltage.At High-level
logic(ON/OFF signal maximum voltage): the allowable leakage current of the switch at 12V is 0.5 mA.
Remote ON/OFF Implementation Circuits
Isolated-Control Remote ON/OFF Level Control UsingTTLOutput
Level Control Using Line Voltage
There are two remote control options available, positive logic and negative logic.
a. Positive Logic:
PXF60 module is turned off at
Low-level logic
PXF60 module is turned on at
High-level logic
b. Negative Logic:
PXF60 module is turned on at
Low-level logic
PXF60 module is turned off at
High-level logic
