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

The device integrates a boost converter to generate the source driver supply voltage (VAVDD), positive and negative charge pump controllers to generate gate driver ON (VGH) and OFF (VGL) voltages, and an 6-channel level shifter in a single IC. The positive charge pump controller supports temperature compensation to reduce VGH at high temperatures.

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

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