UCC28061-Q1 datasheet

Description :

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.
