Pin Definitions

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

(as shown in Typical Application) 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. Recommend to use 0.1 μF BS capacitor.
