Texas Instruments  TPS65155RKPR

The TPS65155 provides an integrated bias and level shifter solution forLCD monitors .

The device integrates a boost converter to generate the source driver supply voltage(VAVDD), positive and negative charge pump controllers to generate gatedriver ON (VGH) and OFF (VGL) voltages, and an6-channel level shifter in a single IC. The positive charge pump controller supports temperaturecompensation to reduce VGH at high temperatures.

In addition to the above functions, the TPS65155 generates an additional active-lowXAO reset output.

Supply sequencing during power-up can be controlled by an externallygenerated enable signal.
