The TPS65175/A 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 but also 6 gamma references, a supply rail for LVDS support, as well as a Vcom reference. A 12-Channel Level Shifter is also integrated. The solution is delivered in a small 7x7mm QFN package.
The TPS65175/A 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. VCC and RST for the T-Con. VDD and HVDD for the Source Driver. VGH and VGL for the Gate Driver or the Level Shifters. A VCOM operational amplifier is also integrated to provide a common plane reference. The VGH and VCOM voltages can be compensated for low and high temperatures. The transition from one programmed value to another is made using an external thermistor connected to the IC. In addition, a 6-channel Gamma Buffer as well as a 12-Channel Level Shifter are integrated. All output rails and delay times are programmable by a two-wire interface: a single BOM (Bill of Material) 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 TPS65175/A. The solution is delivered in a small 7mm x 7mm QFN-56 package.
