TEA19161T: Resonant power supply control IC
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.
