Description

The TPS65178 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 and its programmable dynamic gain. The solution is delivered in a small 6x6mm QFN package.

The TPS65178 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, VCORE and RST for the T-Con. VDD and HVDD for the Source Driver. VGH and VGL for the Gate Driver or the Level Shifter. The VGH voltage can be compensated for low and high temperatures, if GIP (Gate In Panel) technology is used.The transition from one programmed VGH value to another is made using an external thermistor connected to the IC. In addition, a 6-channel Gamma Buffer is integrated as well as the VCOM reference and programmable gain (fixed or dynamic). A VEPI supply rail is also 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 TPS65178. VCORE, VEPI and HVDD are generated by synchronous buck converters which support chip inductors for an optimized solution size. The solution is delivered in a small 6x6mm QFN package.
