Pin Definitions

Pin Name

Description

BS

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

across the high-side switch driver. Recommend to use a 0.1 μF BS capacitor.

GND

Power ground

FB

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

(as shown in Figure 2) to program the output voltage:

VOUT = 0.6 × (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.

IN

Power input

LX

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