The TPS65160 offers a compact power supply solution to provide all four voltages required by thin-film transistor (TFT) LCD panel. With its high current capabilities, the device is ideal for large screen monitor panels and LCD TV applications.
The device can be powered directly from a 12-V input voltage generating the bias voltages VGH and VGL, as well as the source voltage VS and logic voltage for the LCD panels. The device consists of a boost converter to provide the source voltage VS and a step-down converter to provide the logic voltage for the system. A positive and a negative charge-pump driver provide adjustable regulated output voltages VGL and VGH to bias the TFT. Both boost and step-down converters, as well as the charge-pump driver, operate with a fixed switching frequency of 500 kHz or 750 kHz, selectable by the FREQ pin. The TPS65160 includes adjustable power-on sequencing. The device includes safety features like overvoltage protection of the boost converter and short-circuit protection of the buck converter, as well as thermal shutdown. Additionally, the device incorporates a gate drive signal to control an isolation MOSFET switch in series with VS or VGH. See the application circuits at the end of this data sheet.
