Name

Function Description

1

EN1

CH1 turns on/turns off control input. Drive EN above 1.5V to turn on the part. Drive

EN below 0.6V to turn it off. In shutdown, Don’t leave this pin floating.

2

FB1

Feedback input of CH1. Connect FB to the center point of the external resistor divider.

The feedback threshold voltage is 0.6V.

3

IN2

Power input pin of CH1. Recommended to use a 10uF MLCC capacitor

between IN2 pin and GND2 pin.

4

GND2

Ground pin of CH2.

5

SW2

Internal MOSFET switching output of CH2. Connect SW2 pin with a low

pass filter circuit to obtain a stable DC output voltage.

6

EN2

CH1 turns on/turns off control input. Drive EN above 1.5V to turn on the part. Drive

EN below 0.6V to turn it off. In shutdown, Don’t leave this pin floating.

7

FB2

Feedback input of CH2. Connect FB to the center point of the external resistor divider.

The feedback threshold voltage is 0.6V.

8

IN1

Power input pin of CH1. Recommended to use a 10uF MLCC capacitor

between IN1 pin and GND1 pin.

9

GND1

Ground pin of CH1.

10

SW1

Internal MOSFET switching output of CH1. Connect SW1 pin with a low

pass filter circuit to obtain a stable DC output voltage.

11

Exposed Pad

The Exposed Pad must be soldered to the ground plane on the PCB.
