The AAT2822IBK-1-T1 from Skyworks Solutions is a versatile integrated panel power solution designed for TFT-LCD applications. It combines a triple-output DC-DC converter, a WLED backlight driver, and a VCOM buffer within a compact 4x4mm TQFN package.
The device features a 1.3MHz boost converter capable of generating output voltages up to 14.5V with up to 93% efficiency. It also includes two charge pumps for independent regulation of positive (VGH) and negative (VGL) outputs, adjustable up to +30V and down to -30V respectively. The WLED driver supports backlight applications with constant current output and PWM dimming control up to 1kHz.
Designed for reliable operation, the AAT2822IBK-1-T1 includes integrated soft-start and sequencing for all power rails, along with short-circuit, over-voltage, and over-temperature protection. It operates over a wide temperature range of -40°C to +85°C.
This LED driver is suitable for applications requiring precise voltage regulation and backlight control, such as automotive displays and other portable electronic devices.
