UCC28065DR

The UCC28065DR is a highly integrated, dual-phase, interleaved Power Factor Correction (PFC) controller designed by Texas Instruments. It is primarily used in AC-DC converters to improve power factor and reduce harmonic distortion in compliance with global standards. This device is ideal for high-power applications, providing enhanced efficiency and power density.
Key features include a wide input voltage range, advanced current balancing techniques, and a built-in oscillator for phase interleaving. The UCC28065DR also supports Continuous Conduction Mode (CCM) and integrates multiple protective features like over-voltage, under-voltage, and over-current protection to ensure robust operation. Additionally, it offers soft-start functionality to limit inrush current during start-up.
The interleaved operation reduces input and output ripple currents, minimizing the size of passive components. The UCC28065DR’s compact SOIC-16 package and integrated features make it a suitable choice for designing high-performance, compact PFC stages in power supplies for servers, telecom, and other industrial applications.
