TEA19162T/2J

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. The TEA19162T is a Power Factor Correction (PFC) controller. The IC communicates with the TEA19161T on start-up sequence and protections. It also enables a fast latch reset mechanism. To maximize the overall system efficiency, the TEA19161T allows setting the TEA19161T PFC to burst mode at a low output power level. Using the TEA19161T and TEA19162T combo together with the TEA1995T secondary synchronous rectifier controller, a highly efficient and reliable power supply can be designed with a minimum of external components. The target output power is between 90 W and 500 W. The system provides a very low no-load input power (< 75 mW; total system including the TEA19161T/TEA19162T combo and theTEA1995T) and high efficiency from minimum to maximum load. So, no additional low-power supply is required.
