WHITE LED STEP-UP CONVERTER

AP3009

General Description

Features

The AP3009 is an inductor-based DC/DC converter

designed to drive up to six white LEDs in series for

backlight. Only one feedback resistor is needed to con-

trol the LED current and obtain satisfied brightness.

Inherently Uniform LED Current

High Efficiency: 83% Typical

No Need for Extra Schottky Diode

Over Output Voltage Protection

Drives 2 to 6 LEDs

Fast 1.2MHz Switching Frequency

Uses Tiny 1mm Tall Inductor

Requires Only 0.22µF Output Capacitor

A constant frequency 1.2MHz PWM control scheme is

employed in this IC, which means the tiny external

components can be used. In fact, 1mm tall inductor and

0.22µF output capacitor for the typical application is

very appropriate. Additionally, the schottky diode in

boost circuit is integrated in this chip. AP3009 also

provide a disable port to ease its use for different sys-

tems.

Applications

Cellular Phones

Digital Cameras

LCD modules

GPS Receivers

The over output voltage protection is equipped in

AP3009. When any LED is broken or in other abnor-

mal conditions, the output voltage will be clamped to

30V.

PDAs, Handheld Computers

The AP3009 is available in standard SOT-23-6 pack-

age.
