General Description
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.
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 S
2
Cwire 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 conver-
sion 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 cur-
rent shutdown feature disconnects the load from
the input source and reduces quiescent current to
less than 1μA.
The AAT3128 is available in a 14-pin TSOPJW
package.
