G5529 Description
The G5529 includes a high-performance boost regulator, a gate pulse modulator (GPM), a voltage detector, and a V buffer (unity-gain OPA), for activematrix thin-film transistor (TFT) liquid-crystal displays (LCDs). The boost converter provides the regulated supply volt- age for the panel source driver ICs. The converter is a high switching frequency (640kHz or 1.2MHz) currentmode regulator with an integrated 20V...
