The TEA19161T is a fully digital controller for high-efficiency resonant power supplies. Together with the TEA19162T PFC controller and the TEA1995T dual SR controller, a complete resonant power supply can be built which is easy to design and has a very low component count. 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. So, any auxiliary low-power supply can be omitted.
