The TPS65642A device is a compact LCD bias solution primarily intended for use in notebook and tablet PCs. The device comprises two boost converters to supply the source driver and gate driver, or level shifter, of the LCD panel; two buck converters and a low-dropout (LDO) linear regulator to supply the system logic voltages; a programmable VCOM generator with two high-speed amplifiers; 14-channel gamma-voltage correction; and a gate-voltage shaping function.
