RGB LED Fashion Lighting Controller

General Description

Features

The AAT3128 is a total solution controller for RGB LED

fashion lighting. A simplified control scheme greatly reduc-

es design complexity and accelerates time to market.

• 2.7V to 5.5V Input Voltage Range

• Compatible with Common Anode RGB LEDs

• Four S²Cwire Controlled Lighting Moods

• 0~60mA Programmable Current Source

• Low Noise Constant Frequency Operation

• No Inductors

• Small Application Circuit

• Regulated Output Current

• Integrated LED Control Switches

• Automatic Soft-Start

• Less than 1μA Shutdown Current

The AAT3128 contains a high efficiency tri-mode charge

pump DC/DC converter with 1X, 1.5X and 2X modes for

color LED applications. Current source outputs drive two

individual RGB LEDs for color displays, fashion and mood

lighting. With a single-wire S²Cwire interface, an RGB

LED module is easily controlled to display four distinct

lighting mood effects.

Low external parts count (two 1μF flying capacitors and

two small bypass capacitors) and high conversion effi-

ciency make the AAT3128 ideally suited for small bat-

tery-powered portable applications.

Applications

• Color Backlighting for Monochrome LCD Displays

• Color Display Lighting

• Fashion Lighting RGB LEDs

• Mobile Handsets

• MP3 Players

• PDAs

The AAT3128 has a thermal management system to pro-

tect the device in the event of an output short circuit

condition. Built-in soft-start circuitry prevents excessive

inrush current during start-up. A low current shutdown

feature disconnects the load from the input source and

reduces quiescent current to less than 1μA.

• Smart Phones

The AAT3128 is available in a 14-pin TSOPJW package.
