General Description

Features

AP3015/A

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.

The AP3015/A feature a wide input voltage. The oper-

ation voltage is ranged from 1.2Vto 12V (1V to 12V

for AP3015A). A current limited, fixed off-time con-

trol scheme conserves operating current, resulting in

high efficiency over a broad range of load current.

They also feature low quiescent current, switching cur-

rent limiting, low temperature coefficient, etc.

Fewer tiny external components are required in the

applications to save space and lower cost.

Furthermore, to ease its use in differnet systems, a dis-

able terminal is designed to turn on or turn off the chip.

The AP3015/A are available in SOT-23-5 package.
