1

VDD

Supply input. This pin supplies power to all the internal circuitry. A decoupling capacitor to

ground must be placed close to this pin to ensure stable and clean supply.

2

BST

Bootstrap. This is the positive power supply for the internal floating high-side MOSFET driver.

Connect a bypass capacitor between this pin and SW pin.

3

DRVH Floating driver output.

4

SW

Switching node.

5

INH

Control signal input for the floating driver.

6

INL

Control signal input for the low side driver.

7

VSS,

Exposed
