4 Channel Power Supply For LCD TV And Monitor (12V)

The TPS65161 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.
Compared to the TPS65160 and TPS65160A this device offers a higher output current for the step Down Converter and alway connects the positive Charge Pump supply (SUP) to the output. Therefore, in most applications, a simple Charge Pump doubler CAN generates VGH reducing external component count. 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 V(GL) 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 TPS65161 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.
