The UCC28063EVM-723 is a fully assembled and tested circuit for evaluating the UCC28063 natural interleaving transition mode PFC controller. The evaluation module is an off line 300W PFC pre regulator that runs of a universal line input of 85V to 265V RMS and provides a regulated 390V output. The evaluation module demonstrates how the UCC28063 IC can be used in an interleaved transition mode PFC pre regulator.
