UCC28063 Transition-Mode PFC Controller
Texas Instruments' natural interleaving transition-mode PFC controller with improved audible noise immunity
Texas Instruments' UCC28063 is optimized for consumer applications concerned with audible noise elimination, this solution extends the advantages of transition mode – high efficiency with low-cost components – to higher power ratings than previously possible. By utilizing a Natural Interleaving™ technique, both channels operate as masters (that is, there is no slave channel) synchronized to the same frequency. This approach delivers inherently strong matching, faster responses, and ensures that each channel operates in transition mode.
