The LP6263A includes 2-wire IIC interface, two synchronous boost converters for AVDD and VGH, two buck converters for Vcore and VIO, one charge pump for VGL, one LDO regulator, one voltage detector, one high-speed amplifier for programmable VCOM, one high-speed operation amplifier for HAVDD, two high-speed operation amplifiers for GMA, for active-matrix, thin-film transistor, liquid-crystal displays (LCDs).
One synchronous boost converter (AVDD) provides the regulated supply voltage for the panel source driver ICs.
The converter is a high-frequency current-mode regulator with integrated MOSFET that allows the use of ultra-small inductors and ceramic capacitors. It provides fast transient response to pulsed loads while achieving efficiencies over 88%.
