Description
Low Battery Comparator Input. 0.6V Threshold. May not be left floating. If connected to GND, LBO is
working as Power Output OK.
Ground
External Inductor Connector.
Output Voltage. Decouple VOUT with a ceramic capacitor as close as possible to VOUT and GND.
Reference Pin. Connect a 100nF ceramic capacitor to this pin.
Low Battery Comparator Output. Open-drain output.
Enable Pin. Logic controlled shutdown input.
1 = Normal operation;
0 = Shutdown; shutdown current <100nA.
Battery Voltage Input. Decouple VIN with a 22µF ceramic capacitor as close as possible to VIN and
GND.
Exposed Pad. This pad is not connected internally. Can be left floating or connect to GND to achieve an
optimal thermal performance.
