• Manufacturer Part Number: AP6015
• Description: High Efficiency Step-down Low Power Dc-dc Converter
• Manufacturer: Diodes, Inc.

Application Information
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.).
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.
The UVLO prevents the converter from turning on when the voltage on V
