TPS65640RHRR-LCD Bias with Digital VCOM Buffer for Notebook PCs and Tablet PCs

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/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.

All the regulators and VCOM voltage outputs are programmed through I2C interface and stored in the TPS65640 integrated E2PROM. The TPS65640 is available in 5.5mm × 3.5mm, 28 Leads QFN package.
