On/Off Control Functionality
The On/Off Control pin has an internal 10kΩ pull-up resistor to +V
driven with any logic circuit capable of meeting the following drive requirements.
Logic "0" = 0 to +0.8V. Logic "1" = +2.0V to +V
I
can be used. The drive circuit should be rated for more than 13.6V. Applying
a voltage to pin 3 when no input power is applied to the converter can cause
permanent damage to the converter.
