Overview
The TEA1716T, produced by NXP USA Inc., is a highly integrated power management IC that combines a Power Factor Corrector (PFC) controller and a Half-Bridge resonant Converter (HBC) controller in a single multi-chip IC. This integration enables the design of highly efficient and reliable power supplies with a minimal number of external components. The IC supports universal mains supply operation from 70 V to 276 V (AC) and is particularly suited for applications requiring high power factor correction and resonant conversion, such as in LCD and plasma televisions.
