AAT3128

RGB LED Fashion Lighting Controller

™

ChargePump

General Description

Features

The AAT3128 is a total solution controller for RGB

LED fashion lighting. A simplified control scheme

greatly reduces design complexity and accelerates

time to market.

•

2.7V to 5.5V Input Voltage Range

Compatible with Common Anode RGB LEDs

Four S Cwire Controlled Lighting Moods

0~60mA Programmable Current Source

Low Noise Constant Frequency Operation

No Inductors

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

Small Application Circuit

Regulated Output Current

Integrated LED Control Switches

Automatic Soft-Start

single-wire S Cwire interface, an RGB LED module

Less than 1µA Shutdown Current

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 conver-

sion efficiency make the AAT3128 ideally suited for

small battery-powered portable applications.

Applications

•

Color Backlighting for Monochrome

LCD Displays

The AAT3128 has a thermal management system

to protect 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 cur-

rent shutdown feature disconnects the load from

the input source and reduces quiescent current to

less than 1µA.

•

Color Display Lighting

Fashion Lighting RGB LEDs

Mobile Handsets

MP3 Players

PDAs

Smart Phones

The AAT3128 is available in a 14-pin TSOPJW

package.
