TPS65177RHAR

LCD 驱动器 Fully I2C Program. 6-Ch LCD Bias IC

Description

The TPS65177/A provides all supply rails needed by a GIP Gate-in-Panel or non-GIP TFT-LCD panel. All output voltages are I2C programmable.

VIO and VCORE for the T-CON, VAVDD and VHAVDD for the Source Driver and the Gamma Buffer, VGH and VGL for the Gate Driver or the Level Shifter. For use with non-GIP technology Gate Pulse Modulation GPM is implemented, for use with GIP technology the VGH rail can be temperature compensated. Furthermore a High Voltage Stress Mode HVS for VAVDD and VHAVDD and an integrated VAVDD Isolation Switch is implemented. VCORE, VHAVDD, VGH, VGL, GPM and the VGH temperature compensation can be enabled and disabled by I2C programming.
