 Enable (EN)

When EN is on logic low, the AP6015 goes into shutdown mode. In shutdown, all other functions are turned

off. The supply current is reduced to 1uA (Typ.).

 Soft Start

As the enable pin goes high, the soft-start function generates an internal voltage ramp. This causes the

start-up current to slowly raise preventing output voltage overshoot and high inrush currents. The soft-start

duration is typical 1mSec.

 Under Voltage Lock Out (UVLO)

The UVLO prevents the converter from turning on when the voltage on V

is less than typically 1.6V.
