AAT2833/34

240mA Total Display Solution

for Portable Devices

General Description

The AAT2833/34 is a total solution IC for portable

display applications. Based on a tri-mode charge

pump power engine, it is capable of delivering

240mA of output current for white LED (WLED)

backlight and RGB applications. The high conver-

sion efficiency and high level of integration make the

AAT2833/34 an optimal solution for battery life and

size-critical applications.

AnalogicTech's AS

Cwire鈩?(Advanced Simple

Serial Control鈩? serial digital interface is used to

enable, disable, and set current levels for all of the

light emitting diodes (LEDs). Each backlight chan-

nel can be programmed to 16 levels of current, from

a recommended maximum of 30mA programmed by

the R

BSET

resistor. The RGB module can be adjust-

ed to 8 levels of current, up to a recommended max-

imum of 60mA. The RGB module is programmable

with up to 4096 (AAT2833) or 64 (AAT2834)

color/intensity (brightness) combinations.

The AAT2833/34 is offered in a Pb-free, thermally

enhanced 24-pin 4x4x0.75mm TQFN package.
