1. General description
The TEA1742T is a controller for Power Factor Correction (PFC). Its high level of integration allows the design of a cost-effective power supply with a very low number of external ponents. The special built-in green functions provide high efficiency at all power levels. This applies to quasi-resonant operation at high power levels and quasi-resonant operation with valley skipping. The TEA1742T enables highly efficient and reliable supplies with power requirements of up to 500 W, to be designed easily and with the minimum number of external ponents.
