SLVSCE2 –NOVEMBER 2013

LCD Bias With Digital VCOM Buffer for Notebook PCs and Tablet PCs

Check for Samples: TPS65640

FEATURES

DESCRIPTION

The TPS65640 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 or level

shifter; one buck converters or a LDO regulator

alternatively to supply the time controller logic

voltages; a linear negative voltage regulator to supply

gate off voltage or provide negative voltage for

source driver; a programmable VCOM generator with

one high-speed amplifier; a gate voltage shaping

function and two high speed operational amplifiers.
