I

Enable control. Pull high to turn on. Do not float.

Thermal pad (GND)

G

Internally connect to GND. Recommend to connect to a large ground plane for

the improved thermal performance.

SW

I/O

Inductor pin. Connect this pin to the switching node of inductor.

VIN

I

Power input.

FB

O

Output feedback pin. Connect this pin to the center point of the output resistor

divider to program the output voltage:

VOUT = 0.6 × (1 + R1/R2).

PG

O

Power good indicator. When the output voltage exceeds 95% of regulation point,

it becomes open drain; low otherwise.

PGND

G

Power ground. Must connect this pin to the system ground on the board.

SGND

G

Signal ground. Must connect this pin to the system ground on the board.
