Overview
The UCC28060DR, produced by Texas Instruments, is a natural interleaved dual-phase transition-mode Power Factor Correction (PFC) controller. This integrated circuit is optimized for high-volume consumer applications, offering high efficiency with low-cost components. It utilizes a Natural Interleaving technique, where both channels operate as masters synchronized to the same frequency, ensuring strong matching, faster responses, and operation in transition mode. The UCC28060DR is designed to enhance efficiency and design flexibility over traditional single-phase continuous conduction mode controllers.
