PINOUT DESCRIPTION

PIN #

NAME

DESCRIPTION

1

BST

High side power transistor gate drive boost input

2

VIN

Power input, the input capacitor should be placed as close to VIN and GND pin as possible

3

SW

Power switching node to connect inductor

4

GND

Ground.

5

FB

Feedback input with reference voltage set to 0.923

6

COMP

Compensation node. A serial RC connected to this pin is required to maintain the Buck

converter control loop stable.

7

EN

Enable input. Setting it to high level or connecting to Vin via a resistor may turn on the chip,

while setting it to ground level will turn off the chip.

8

SS

Soft-start node. Connecting a 0.1uF capacitor to ground make the Buck converter output rise

smoothly.
