Remote ON/OFF Control
The remote ON/OFF pin allows the user to turn the DC/DC power module on and off from a remote switch device.
The ON/OFF input can be switched by a number of switching devices. Figure 5 gives several examples of
acceptable configurations. The remote ON/OFF pin is an open collector/drain logic input signal that is referenced
to –Vin. A logic High on the remote ON/OFF pin turns the module ON and a logic Low on the remote ON/OFF
pin turns the module OFF. If the remote ON/OFF feature is not being used please make an open circuit between
the ON/OFF pin and the –input pin to turn the module on.
