AAT2830/31
800mA Total Display Solution
for Portable Devices
General Description
The AAT2830/31 is a total solution IC for portable dis-
play applications. Based on a tri-mode charge pump
power engine, it is capable of delivering 800mA of
output current with individual driving circuitries for
light emitting diode (LED) backlights, photo flash, and
RGB. The high conversion efficiency and high level
of integration make the AAT2830/31 the optimum
solution for battery life and size-critical applications.
AnalogicTech's AS

Cwire鈩?(Advanced Simple Serial
Control鈩? serial digital input is used to enable, dis-
able, and set current for all of the outputs. Each back-
light LED output can be programmed to 30mA over 16
discrete steps. The AAT2830/31 can also deliver up to
600mA to drive flash LEDs over four individual chan-
nels, with excellent current matching between chan-
nels. A built-in safety timer function allows easy, one-
trigger system control for photo flash applications.
The RGB output can be adjusted to handle up to
60mA, and the AS
2
Cwire signal can drive the RGB
module in up to 4096 (AAT2830) or 64 (AAT2831)
color intensity combinations.
The AAT2830/31 is available in a Pb-free, thermal-
ly-enhanced 24-pin 4x4x0.75mm TQFN package.
