The TEA2376 is a digital configurable two-phase interleaved PFC controller for high-efficiency power supplies. The PFC operates in discontinuous conduction mode or quasi-resonant mode with valley switching to optimize efficiency. The TEA2376 is suitable for TV, computing, server and industrial power supplies. For low-load operation with good efficiency, phase shedding and burst mode operation are included. The TEA2376 supports a high power factor and a low THD and contains many protections which can be configured independently by a GUI. The TEA2376 allows an easy to design, highly efficient, reliable interleaved PFC with a low external component count for power levels up to typically 1000 W.
