The AAT2801 is a member of AnalogicTech's Total Power Management ICTM (TPMICTM) product family. It has a dual charge pump architecture designed to support both the white LED backlight and flash applications for systems operating with Lithium-Ion batteries. The backlight charge pump provides power required to drive up to four LEDs. To maximize power efficiency, it automatically selects 1X, 1.5X, or 2X mode. The device produces current levels up to 30mA on each of its four current source outputs. AnalogicTech's Simple Serial ControlTM (S2CwireTM) interface is used to enable, disable, and set the LED drive current with a 32-level logarithmic scale LED brightness control.
