1 pcs : UCC28063DR - Power Factor Correction - PFC NATURAL INTERLEAVING TRAN MODE PFC CNTRLR

UCC28063 PFC Controller Texas Instruments UCC28063 Natural Interleaving™ Transition-Mode PFC Controller with Improved Audible Noise Immunity is optimized for consumer applications concerned with audible noise elimination. This TI 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 of the TI UCC28063 operate as masters synchronized to the same frequency. This approach delivers inherently strong matching and faster responses and ensures that each channel operates in transition mode. Expanded system level protections feature input brownout and dropout recovery, output over-voltage, open-loop, overload, soft-start, phase-fail detection, and thermal shutdown. The additional FailSafe over-voltage protection feature protects against shorts to an intermediate voltage that, if undetected, could lead to catastrophic device failure.
