Remote ON/OFF Control
The Remote ON/OFFPin is used to turn on andoffthe DC-DCconverter. The usermustuse a switchto control
the logic voltage (highor low level) of the ON /OFF pin, referenced to Vi(-).The switchcan bea opencollector
transistor, FET, or Opto-Coupler, thatis capableof sinkingup to 0.5 mAat a low-level logic Voltage. Forhigh-level logic
of the ON/OFF signal (maximum voltage): the allowable leakage current of theswitchat 12Vis 0.5 mA.
