TEA2376DT
description
The TEA2376DT 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 TEA2376DT enables the building of an interleaved power factor controller, which is easy to design with a low external ponent count.
The TEA2376DT is available in a low profile and narrow body-width SO14.
The digital architecture of the TEA2376DT is based on a high-speed configurable hardware state machine ensuring reliable real-time performance. To meet specific application requirements, many operation and protection settings of the PFC controller can be adjusted by loading new settings into the device with I2C during power supply development.
For a high power factor and a low THD, input current shaping is used. A notch filter allows a faster transient response by suppressing the mains frequency ponent in the regulation loop, while...
