The TEA2376 is a digital configurable two-phase interleaved PFC controller for high-efficiency power supplies, available in SO14 and SO10 package. 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. The TEA2376DB1602 is a 300 W/395 V interleaved PFC power supply demo board. It showcases the TEA2376DT interleaved PFC controller IC and the TEA2209 active bridge controller IC. With a Windows OS PC in combination with the RDK01DB1563 USB I²C interface, the behavior of the TEA2376 controller can be modified by settings and status information of the power supply can be collected.
