1 General description

The TEA2376BT 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 TEA2376BT enables the building of an interleaved power factor controller, which is easy to design with a low external component count.

The TEA2376BT is available in a low profile and narrow body-width SO14.

The digital architecture of the TEA2376BT 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 component in the regulation loop, while maintaining a low THD. For low-load operation with good efficiency, phase shedding and burst mode operation are included. To meet the efficiency and standby power regulations of Energy Star, the Department of Energy, the Eco-design directive of the European Union, the European Code of Conduct, and other guidelines, the power consumption of the IC is reduced in burst mode operation. The TEA2376BT contains many protections, like internal and external overtemperature protection (OTP), overcurrent protection (OCP), dual overvoltage protection (OVP), inrush current protection (ICP), pin open, pin short protection, and phase fail protection. The protections can be configured independently and using programmable parameters.

The TEA2376BT allows an easy to design, highly efficient, and reliable interleaved PFC, for power levels up typically to 1000 W1.
