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 VCOM generator with two high-speed amplifiers; 14-channel  
gamma-voltage correction; and a gate-voltage shaping function.
