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
