Note 1: Minimum operating input voltage is fixed by the battery’s ability to provide necessary power at that

(terminal) voltage. Below this voltage, the battery fails to deliver required power as it enters into deeply

discharged state. This voltage can be lower if the required duty cycle is less.

Note 2: When the input voltage is greater than the output voltage regulation point, the part operates in track

mode (see Track Mode).

Note 3: For applications where V

> 4.3V, an external Schottky diode is recommended.
