Pin Definitions

Pin Name

Description

GND

Power ground

SW

Inductor pin. Connect this pin to the switching node of inductor.

VIN

Power input

FB

Output feedback pin. Connect this pin to the center point of the output resistor divider to program

the output voltage:

VOUT = 0.765 × (1 + R1/R2).Add optional C2 (10 pF ~ 47 pF) to speed up the transient response.

EN

Enable control. Pull high to turn on. Do not float.

BS

Bootstrap. Connect a capacitor and a resistor between SW and BS pins to form a floating supply

across the high-side switch driver.
