Texas Instruments TPS65155
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 6channel level shifter in a single IC. The positive charge pump controller supports temperature compensation to reduce VGH at high temperatures.| Part No. | TPS65155 |
