General DescriptionThe G5567 DC-DC converter provides six regulatedvoltages required by thin-film transistor (TFT) liquidcrystal displays (LCD) panels. All output voltages areprogrammable.The VIO and VCORE buck converters are for the T-CON.The VAVDD boost converter and VHAVDD buck convertersare for the source driver and Gamma buffer. Chargepump VGH and VGL are for the gate driver or levelshifter. VGH voltage is with temperature compensationfor the Gate in Panel (GIP) technology.Also, a high voltage stress (HVS) mode for the VAVDDand a VAVDD isolation switch is integrated.G5567 offers high current capabilities, and is ideal forlarge screen LCD monitors panels and TV applicationswith 12V supply voltage.
