Function
Switch pin. This is the drain of the internal power switch. For
minimum EMI, minimize the trace area connected to this pin.
Ground pin. Connect pin 2 to ground.
LED (cathode) connection pin.
Shutdown pin.
Input supply pin. This pin should be bypassed with a
capacitor to ground. A 1µF capacitor mounted close to the
pin is recommended.
