DESCRIPTION  
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.
