Overview
The TEA19162T, produced by NXP USA Inc., is a Power Factor Correction (PFC) controller integrated into a combined controller (combo) IC, designed for resonant topologies. This controller works in conjunction with the TEA19161T to provide high efficiency across all power levels. Together with the TEA1995T dual LLC resonant SR controller, it enables the construction of a cost-effective and highly efficient resonant power supply that complies with various efficiency regulations, including those set by Energy Star, the Department of Energy (DoE), the Eco-design Directive of the European Union, and the European Code of Conduct.
