Overview
The UCC28060DG4, produced by Texas Instruments, is a Natural Interleaved Dual-Phase Transition-Mode Power Factor Correction (PFC) Controller. This component is optimized for high-volume consumer applications, extending 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 controller operate as masters, synchronized to the same frequency, ensuring strong matching, faster responses, and operation in transition mode.
