Description

WL-CSP

TDFN

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

GND, LBO is working as Power Output OK.

LBI

Ground

GND

External Inductor Connector.

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

and GND.

VOUT

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

Low Battery Comparator Output. Open-drain output.

REF

LBO

Enable Pin. Logic controlled shutdown input.

1 = Normal operation;

0 = Shutdown; shutdown current <100nA.

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

and GND.

VIN

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

to achieve an optimal thermal performance.
