The TPS65110/11 is a very compact power supply solution providing the three voltages required by many LTPS LCD displays. All three regulated outputs are generated using a charge pump topology. The VCC charge pump provides precise, high efficiency, and very low ripple dc/dc conversion for the LCD analog power. The VCC boost ratio (x1.0, x1.33, x1.5, and x2.0.
