Functional Pin Description

Pin No.

Pin Name

Pin Function

1

SS

Soft-Start Control Input. SS control the soft-start period. Connect a capacitor

from SS to GND to set the soft-start period.

2

VIN

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

large 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 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 = 0.8V.
