TPS65148,pdf( Features)

The TPS65168 provides a simple and economic power supply soluTIon for a wide variety of LCD bias applicaTIons. The device provides all supply rails needed by a TFT-LCD panel. V_I/O, V_CORE and RST for the T-Con. V_DD and HV_DD for the Source Driver and the Gamma Buffer. V_GH and V_GL for the Gate Driver or the Level Shifter. The V_GH voltage can be compensated for low and high adjustable temperatures, if GIP technology is used. The transiTIon from one programmed V_GH value to another is made using an external thermistor connected to the IC. All output rails and delay TImes are programmable by a Two-Wire interface: a single BOM can cover several panel types and sizes whose desired output levels can be programmed in production and stored in a non-volatile memory embedded into the TPS65168.
