Functional Pin Description

Pin No.

Pin Name

Pin Function

1

PG

Power good output. This pin is an open drain which can be connected to

PVCC by a resistor. If output voltage achieve 90% of the normal voltage, the

PG pin will go high after 400

s delay.

2

VIN

Power input. Support 4.5V to17V Input Voltage. Must bypass with a ceramic

capacitor at this pin.

3

SW

Switch node. Connect to external L-C filter.

4

GND

System ground.

5

BOOT

Bootstrap supply for high-side gate driver. Connect a 0.1

F ceramic capacitor

between the BOOT and SW pins.

6

EN/SYNC

Enable control input. High = Enable. Apply an external clock to adjust the

switching frequency. If using pull high resistor connected to VIN, the

recommended value range is 60k

 to 300k.

7

PVCC

5V Bias supply output

. Connect a minimum of 0.1F capacitor to ground.

8

FB

Feedback voltage input. The pin is used to set the output voltage of the

converter to regulate to the desired voltage via a resistive divider. Feedback

reference = 0.807V.
