SW

O

Switch node. This pin is connected to the output inductor.

13, 14

PGND

S

Power Ground. This pin serves as a separated ground for the MOSFET

drivers and should be connected to the system’s power ground plane.

15, 16

PVin

S

Input supply for the power stage.

Exposed

Pad

-

Exposed pad needs to be connected to PGND with PCB layout design.

Thermal via holes can be placed on the exposed pad to aid thermal

dissipation.
