TPS65148 描述
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. VI/O, VCORE and RST for the T-Con. VDD and HVDD for the Source Driver and the Gamma Buffer. VGH and VGL for the Gate Driver or the Level Shifter. The VGH voltage can be compensated for low and high adjustable temperatures, if GIP technology is used. The transition from one programmed VGH 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.
