Pin No.

Pin Name

Pin Function

1

EN

Enable control input. Connect this pin to logic high can enable the device and

connect this pin to GND can disable the device.

2

VOUT

Output voltage controlled by VID.

3

PVCC

5V power supply output. A capacitor (typical 1

F) should be connected to GND.

4

SDA

Data I/O pin.

5

SCL

Clock I/O pin.

6

SW

Switch output.

7

BOOT

Bootstrap. This capacitor is needed to drive the power switch's gate above the

supply voltage. It is connected between SW and BOOT pins to form a floating

supply across the power switch driver. A 0.1

F capacitor is recommended for

use.

8

VIN

Power input and connected to high-side MOSFET drain.

9 (Exposed Pad)

GND

GND. The exposed pad must be soldered to a large PCB and connected to

GND for maximum thermal dissipation.
