General Description
The AP3015/A are Pulse Frequency Modulation (PFM) DC/DC converters. These two devices are func
tionally equivalent except the switching current limit. The AP3015 is designed for higher power systems with 350mA current limit, and the AP3015A is for lower power systems with 100mA current limit.
