AAT2845A | Four-Channel Backlight Driver With Dual LDOs

The AAT2845A is a highly integrated power solution for single-cell lithium-ion-based LCD Display applications. It includes a four-channel LED backlight driver and two integrated 200mA LDOs as additional power supplies for Display and camera related chipsets. The backlight driver is a low noise, constant frequency Charge Pump DC/DC converter that uses a tri-mode load Switch (1X), fractional (1.5X), and doubling (2X) conversion to maximize efficiency. Each of the four channels is capable of driving up to 20mA per channel. AnalogicTech's SCwire (Simple Serial Control) serial digital input is used to enable, disable, and set current for each LED with 16 available settings down to 50A. The low current mode supply current CAN be as low as 50A to save power and maintain high efficiency. Each LED output is equipped with built-in protection for short-circuit and auto-disable functions. Built-in soft-start circuitry prevents excessive inrush current during start-up. A low current shutdown feature disconnects the load from VIN and reduces quiescent current to less than 1A. The AAT2845A is available in a Pb-free, thermally-enhanced 20-pin 3x4mm TQFN package
