MICRO POWER STEP-UP DC-DC CONVERTER

AP3015/A

General Description

Features

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.

Low Quiescent Current

In Active Mode (Not Switching): 17µA Typical

In Shutdown Mode: <1µA

Low Operating V

1.2V Typical for AP3015

1.0V Typical for AP3015A

Low V

Switch

CESAT

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.

200mV Typical at 300mA for AP3015

70mV Typical at 70mA for AP3015A

High Output Voltage: up to 34V

Fixed Off-Time Control

Switching Current Limiting

350mA Typical for AP3015

100mA Typical for AP3015A

Operating Temperature Range: -40^oC to 85^oC

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.

Applications

MP3, MP4

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

Battery Power Supply System

LCD/OLED Bias Supply

Handheld Device

Portable Communication Device
