Remote ON/OFF Control
The Remote ON/OFF Pin is used to turn on and off the DC-
DC converter. The user must use a switch to control
the logic voltage (high or low level) of the ON/OFF pin, referenced to -Vi. The switch can be open collector transi
stor,
FET or Opto-Coupler that is capable of sinking up to 0.5 mA at low-level logic Voltage. High-
level logic of the
ON/OFF signal (maximum voltage): theallowable leakage current ofthe switch at 12V is 0.5mA.

There are two remote control options available, Positive Logicand Negative Logic.
a. Positive logic:

module is turned off
using Low-level logic
PXE30-xxWSxx moduleis turned on
using High-level logic
b. Negative logic:
PXE30-xxWSxx moduleis turned on
using Low-level logic
