General Description

The G5529 includes a high-performance boost regulator, a gate pulse modulator (GPM), a voltage detector, and a VCOM buffer (unity-gain OPA), for activematrix thin-film transistor (TFT) liquid-crystal displays (LCDs).

The boost converter provides the regulated supply volt- Pin Configuration age for the panel source driver ICs.

The converter is a high switching frequency (640kHz or 1.2MHz) currentmode regulator with an integrated 20V N-Channel 0.2Ω MOSFET that allows the use of ultra-small inductors and ceramic capacitors.
