G5524A Overview
The G5524A includes a high-performance boost regulator, 4-channel LED driver, a low dropout linear regulator (LDO), a gate pulse modulator (GPM), a voltage detector, a V buffer (unity-gain OPA), and a VGH charge pump controller for active-matrix thin-film transistor (TFT) liquid-crystal displays (LCDs). The boost converter provides the regulated supply voltage for the panel source driver ICs. The converter is a high...
