The AAT2823IBK-T1 from Skyworks Solutions is a versatile integrated panel power solution designed for TFT-LCD displays. It incorporates a triple-output DC-DC converter, a WLED backlight driver, and a VCOM buffer, all within a compact 4mm x 4mm TQFN package.
This device features a 1.3MHz fixed-frequency boost converter capable of generating output voltages up to 14.5V with efficiencies up to 93%. It also includes two charge pumps for independent positive (VGH) and negative (VGL) outputs, regulating voltages up to +30V and down to -30V respectively. The WLED driver provides a constant current output suitable for backlight applications, supporting up to seven white LEDs in series or 39 in a parallel/series configuration. LED brightness is controlled via PWM up to 1kHz.
The AAT2823IBK-T1 operates over an input supply range of 2.5V to 5.5V and has an operating temperature range of -40°C to +85°C. Its integrated features include soft-start, sequencing of all rails, and protection against short-circuit, over-voltage, and over-temperature conditions. The high slew rate operational amplifier is ideal for VCOM buffering and gain adjustment.
Packaged in a 24-pin TQFN, the AAT2823IBK-T1 is designed for surface mounting. Its applications include automotive systems and general backlight solutions for displays ranging from 5" to 10".
