FUNCTION DESCRIPTIONS

Pin Functions

Vcc

It provides the IC switching regulator with positive input supply. This pin is used to supply the switching currents

needed by the regulator and a suitable input bypass capacitor must be connected at this pin.

GND

Circuit ground.

SW

area connected to this pin.

Feedback

Senses the regulated output voltage to complete the feedback loop.

EN

Using logic level signals to allow the switching regulator circuit to be shutdown, which dropping the total input

supply current to approximately 10uA. Shut the regulator down through pulling this pin below a threshold voltage of
