TEA19162T中文资料PFC控制器数据手册恩XP规格书

描述 Description

The TEA19162T and TEA19161T are a 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 theTEA19161T 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 TEA19162T PFC to burst mode at a low output power level.
The TEA19162HT/2 is recommended for applications that require high-power factor performance, like energy star 80+ gold, platinum or titanium.
