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 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.
