Application Information
Provides the gate voltage for the high side NFET.
Pins are not electrically connected inside the chip. Pins do function as
thermal conductor.
Inverting input to the internal voltage error amplifier.
When pulled low regulator turns off.
Provide good capacitive decoupling between VIN and this pin
Input to the regulator. Operates from 4.5V to 42V.
Attaches to the switch node
