5 CHANNEL CHARGE PUMP CURRENT SINK FOR LED DRIVER

AP3615

Features

General Description

•

Regulated Output Current with ±3% Matching

Drives up to 5 WLEDs at 20mA Each

16 Steps Brightness Control Using Pulse Signal

Dimming

Wide Operating Voltage Range: 2.8V to 5.5V

High Operating Frequency: 1MHz

Auto 1x/1.5x Charge Pump Mode Selection

Built-in Soft-start

The AP3615 is a step-up DC-DC converter based on

1x/1.5x charge pump and low dropout current sink,

which helps it maintain the highest efficiency. The

AP3615 is specially designed to drive up to 5

WLEDs in backlight display.

•

The AP3615 provides up to 20mA current for each

WLED. There are totally 16 steps of current control,

which is achieved through a digital pulse dimming

function on EN pin. Additionally, 1MHz high

switching frequency enables the use of small external

capacitors. Internal soft-start circuitry prevents

excessive inrush current during start-up and mode

transition.

Output Over Voltage Protection

Built-in UVLO

Built-in OTSD

Operating Temperature Range: -40°C to 85°C

Applications

The supply voltage of AP3615 ranges from 2.8V to

5.5V which make it ideally suit for applications

•

Mobile Phone

PDA

MP3/4

The AP3615 is available in the tiny package of

QFN-3×3-16.
