Description

1

LX

Switch pin. Connect this pin to inductor/diode here.

2

GDN

GND

3

FB

Feedback Input. The device senses feedback voltage via FB and regulate the voltage at

1.23V. Connecting FB wi th a resistor‐divider from the output that sets the output voltage.

4

EN

Enable Control Input. Forcing this pin above 1.0V enables the device. Forcing this pin

below 0.4V to shut it down. In shutdown, all functions are disabled to decrease the supply

current below 1μA. Do not left this pin floating.

5

IN

Main Supply Pin. Must be closely decoupled to GND with a 2.2μF or greater ceramic

capacitor.
