TFT-LCD DC-DC Converter with WLED Driver and VCOM Buffer

The AAT2822-AAT2825 family of integrated panel power solutions provides the regulated voltages required by an active-matrix thin-film transistor (TFT) liquid-crystal display (LCD). The AAT2822 includes a triple-output DC/DC converter, a LED backlight driver, and a VCOM buffer in a 4 mm x 4mm TQFN pa ·Efficient:? The AAT2822’s boost converter architecture improves efficiency to charge pump only implementation.\n·Flexible:? The 28V WLED backlight driver supports high voltage serial and parallel configured LED strings.\n·Powerful:? The backlight driver can deliver up to 260mA of continuous current;
