Texas Instruments  TPS65642YFFR

The TPS65642 is a compact LCD bias solution primarily intended for use in Notebook and Tablet PCs. The device comprises two boost converters to supply the LCD panel’s source driver and gate driver/level shifter; two buck converters and an LDO linear regulator to supply the system’s logic voltages; a programmable VCOM generator with two high-speed amplifiers; 14-channel gamma voltage correction; and a gate voltage shaping function.
