The TPS65175B/C 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. The device also integrates a VCOM_DAC rail providing the reference for an external non-inverting operational amplifier input. A 12-Channel Level Shifter is also integrated. The solution is delivered in a small 7×7 mm QFN package.

The TPS65175B/C 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 / VCOM_DAC 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 TPS65175B/C. The solution is delivered in a small 7 mm × 7 mm QFN-56 package.
