Pin Number

Pin Name

Description

1LBI

Low Battery Comparator Input. 0.6V Threshold. May not be left floating. If connected to GND, LBO is

working as Power Output OK.

2GND

Ground

3LX

External Inductor Connector.

4VOUT

Output Voltage. Decouple VOUT with a ceramic capacitor as close as possible to VOUT and GND.

5REF

Reference Pin. Connect a 100nF ceramic capacitor to this pin.

6LBO

Low Battery Comparator Output. Open-drain output.

7EN

Enable Pin. Logic controlled shutdown input.

1 = Normal operation;

0 = Shutdown; shutdown current <100nA.

8VIN

Battery Voltage Input. Decouple VIN with a 22µF ceramic capacitor as close as possible to VIN and

GND.

9NC

Exposed Pad. This pad is not connected internally. Can be left floating or connect to GND to achieve an

optimal thermal performance.
