Description

1

LBI

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

working as Power Output OK.

2

GND

Ground

3

LX

External Inductor Connector.

4VOUT

Output Voltage. Decouple VOUT with a 22µF ceramic capacitor as close as possible to VOUT and

GND.

5

REF

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.

8

VIN

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

GND.

9

NC

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

an optimal thermal performance.
