The TPS65177 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.
A single BOM (Bill of Materials) can cover several panel types and sizes whose desired output voltage levels can be programmed in production and stored in a non-volatile integrated memory.
