1.3 Description

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 V_COMgenerator with two high-speed amplifiers; 14-channel

gamma-voltage correction; and a gate-voltage shaping function.
