The TEA19161T and TEA19162T are combined controller 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.
Resonant topologies show excellent efficiencies at high-power levels, while at lower levels its efficiency reduces because of the relatively high magnetizing current and switching losses. Therefore, at low-power levels the TEA19161T (LLC) switches to a, newly introduced, low-power mode. This mode operates in the power region between continuous switching (also called high-power mode) and burst mode.
The TEA19161T is designed to cooperate with the TEA19162T Power Factor Control (PFC) controller. To ensure communications regarding start-up and protections, the TEA19161T contains a digital control. The digital control also enables a fast latch reset mechanism. To maximize the overall system efficiency at low output power levels, the TEA19161T sets the TEA19162T to operate in burst mode.
Using the TEA19161T/TEA19162T/TEA1995T combination, a highly efficient and reliable power supply, providing 90 W to 500 W, can be designed with a minimum of external components. The system provides a very low no-load input power (< 75 mW; total system including the TEA19161T/TEA19162T/TEA1995T combination) and high efficiency from minimum to maximum load. So, any additional low-power supply can be omitted.
