Power Switch Pin. Ties to the drains of the PMOS synchronous rectifier and the
NMOS switch.
Ground Pin
Feedback Input Pin. Connect FB to the center point of the external resistor divider.
The feedback threshold voltage is 1.23V.
Shutdown Signal Input. Logic high enables the IC. Logic low disables the IC. Shutdown
current is <1µA.
Power Output Pin. Tied to the source of the PMOS synchronous rectifier.
Power Supply Input. Must be closely decoupled to GND, Pin 2, with a 4.7µF or greater
ceramic capacitor.
