General Description

The G2523 includes a high-performance boost regulator, a buck-boost controller, a high voltage charge pump regulator, 3 VCOM buffers (unity-gain OPA) for active-matrix thin-film transistor (TFT) liquid-crystal displays (LCDs).

The boost regulator provides the regulated supply voltage for the panel source driver ICs.

It is a high switching frequency (1.2MHz) current-mode regulator with an integrated 20V/0.15Ω NMOS switch that allows the use of ultra small inductors and ceramic capacitors.
