The RT6908 provides a complete set of programmable multi-functional power solution for TFT LCD panel. The RT6908 contains a step-up converter for main power and step-down controllers to provide the logic voltages for the system. Moreover, a positive charge pump regulator provides the adjustable gate-high voltage, VGH; a negative charge pump regulator provides the gate-low voltage, VGL. AVDD, VGH and VGL outputs and power sequence can be programmable through I2C interface.
With its high current capabilities, the device is ideal for large screen monitor panels and LCD TV applications with 12V supply voltage. The RT6908 is available in a WQFN-40L 5x5 package.
