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) is automatically set based on input and output voltage conditions. The VCC output assures 16 mA of current by using three 0.22-µF flying capacitors. If the required output current is smaller, smaller capacitors can be applied.

The VDD charge pump provides a higher positive voltage, and the VSS charge pump provides the negative output voltage.
