AAT3103

ChargePump^TM

3-Channel Charge-Pump LED Driver

General Description

Features

The AAT3103 is a constant frequency charge-pump based

current-source white LED driver capable of driving one to

three LEDs up to 30mA, each. The charge pumps auto-

matically switch between 1x mode and 2x mode to main-

tain the highest efficiency and optimal LED current accu-

racy and matching. A low external parts count (one 1μF

flying capacitor, two small 1μF capacitors at IN and OUT

and one current setting resistor) makes the AAT3103 ide-

ally suited for small battery-powered applications.

• Source WLED Driver, up to 3 LEDs at up to 30mA, each

• Automatic Switching Between 1x and 2x Modes

• 900KHz Switching Frequency

• Linear LED Output Current Control

Single-wire, S²Cwire Interface

▪

• ±10% LED Output Current Accuracy

• ±3% LED Output Current Matching

• Low-current Shutdown Mode

• Built-in Short Circuit and Thermal Protection

• Automatic Soft-start

The AAT3103-1/-2 uses AnalogicTech's Simple Serial

Control™ (S²Cwire™) interface to enable, disable, and

program the LED driving current. The AAT3103-4 employs

a Pulse Width Modulation (PWM) signal with up to 50kHz

frequency, 10% to 100% duty cycle to program the LED

current. A low-current shutdown feature disconnects the

load from IN and reduces quiescent current to less than

1ꢀA. Built-in soft-start circuitry prevents excessive inrush

current during start-up. Integrated short circuit and ther-

mal protection circuitry protects the device from damage.

• 2x2.1mm SC70JW-10 Package

Applications

• Cordless Phone Handsets

• Mobile Phone Handsets

• MP3 and PMP Players

• Digital Cameras

The AAT3103 is available in a 2x2.1mm thermally

enhanced Pb-free 10-lead SC70JW-10 package.
