Description
Input voltage power pin. Inductor charging current passes through this pin.
Internal supply voltage. Control circuitry powered from this pin.
Open drain battery low output. (V IN -V O ) less than 300mV pulls this
node to ground. (V IN -V O ) above threshold, this node is open.
Digital mode control input. See table 1 for definition.
Digital mode control input. See table 1 for definition.
External feedback network input connection. Connect a resistor from
FB to ground and FB to V OUT to set the output voltage. This pin
regulates to the internal bandgap reference voltage of 0.8V.
Output voltage sense pin. Used by the timing circuit to set minimum on
and off times.
Internal ground pin. Control circuitry returns current to this pin.
Power ground pin. Synchronous rectifier current returns through this pin.
Inductor switching node. Inductor tied between this pin and the output
capacitor to create regulated output voltage.
Operating Mode
Shutdown. All internal circuitry is disabled and the power switches are opened.
Device enabled, falling UVLO threshold =2.70V
Device enabled, falling UVLO threshold =2.85V
Device enabled, falling UVLO threshold =3.00V
