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.
