TEA19162T/3 PFC controllerRev. 3 7 May 2018 Product data sheet 1 General descriptionThe TEA19162T and TEA19161T are combined controller (combo) ICs for resonanttopologies including PFC. They provide high efficiency at all power levels. Togetherwith the TEA1995T dual LLC resonant SR controller , a cost-effective resonant powersupply 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, theEuropean Code of Conduct, and other TEA19162T is a Power Factor Correction (PFC) controller . The IC communicateswith the TEA19161T on start-up sequence and protections. It also enables a fast latchreset mechanism. To maximize the overall system efficiency, the TEA19161T allowssetting the TEA19161T PFC to burst mode at a low output power the TEA19161T and TEA19162T combo together with the TEA1995T secondarysynchronous rectifier controller , a highly efficient and reliable power supply can bedesigned with a minimum of external components.
