ON/OFF pin is pulled up to Vin inside of the DC-DC Converter. If ON/OFF pin is left open,
the DC-DC Converter shall be “ON”. This pin will be pulled down to GND inside the
DC-DC Converter when OCP or OTP events occur. Please do NOT connect this pin to
Vin with low impedance line, so as not to damage the converter..
