The TEA19162T and TEA19161T are combined controller (combo) ICs for resonant topologies including PFC. They provide high efficiency at all power levels. Together with the TEA1995T dual LLC resonant SR controller, a cost-effective resonant power supply can be built. This power supply meets the efficiency regulations of Energy Star, the Department of Energy (DoE), the Eco-design Directive of the European Union, the European Code of Conduct, and other guidelines.
