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.

V_(IO) and V_(CORE) for the T-CON, V_(AVDD) and V_(HAVDD) for the Source Driver and the Gamma Buffer, V_(GH) and V_(GL) 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 V_(GH)rail can be temperature compensated. Furthermore a High Voltage Stress Mode (HVS) for V_(AVDD) and V_(HAVDD) and an integrated V_(AVDD) Isolation Switch is implemented. V_(CORE), V_(HAVDD), V_(GH), V_(GL), GPM and the V_(GH) 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.
