Function

Input power pin; connected to the source of the P-channel MOSFET. Connect to the input

capacitor.

Input bias voltage for the converter.

Non-power signal ground pin.

Feedback input pin. Connect this pin to an external resistive divider for adjustable output.

No connect.

Enable pin. A logic high enables normal operation. A logic low shuts down the converter.

Switching node. Connect the inductor to this pin. It is connected internally to the drain of

both high- and low-side MOSFETs.

Input power return pin; connected to the source of the N-channel MOSFET. Connect to the

output and input capacitor return.

Exposed paddle (bottom): connect to ground directly beneath the package.
