Step-Down TFT-LCD DC-DC Converter: AAT2823
The AAT2823 is part of a family of integrated panel power converters with WLED drivers and VCOM buffers. This converter provides the regulated voltages required by TFTs and LCDs, and is equipped with a triple output DC-DC converter, a LED backlight driver, and a VCOM buffer in a 4 mm x 4 mm TQFN package.
The AAT2823 has two charge pumps that independently regulate a positive output (VGH) and a negative output (VGL). The high efficiency backlight driver provides a constant current output capable of boosting up to 28V, and is an ideal power solution for backlight applications with up to seven white LEDs in a series or up to 39 white LEDs in a parallel series configuration. These converters are also good for use in medical applications involving defibrillators, heart monitors, hearing aids, and other radiation and clinical equipment.
