AAT3128
AAT3128 is RGB LED Fashion Lighting Controller manufactured by Skyworks Solutions.
Description
The AAT3128 is a total solution controller for RGB LED fashion lighting. A simplified control scheme greatly reduces design plexity and accelerates time to market.
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 efficiency make the AAT3128 ideally suited for small battery-powered portable applications.
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 current shutdown feature disconnects the load from...
