UCC28056DBVT TI PFC Controller | SOT-23-6 | 65kHz, 10.5V Startup

Product Overview

The UCC28056DBVT is a high-performance transition-mode power factor correction (PFC) controller from Texas Instruments. It is designed to achieve near-unity power factor and low total harmonic distortion (THD) in AC-DC power supplies. The device integrates advanced features such as frequency dithering, burst mode operation, and comprehensive protection functions, making it ideal for applications requiring high efficiency and reliability. Housed in a compact SOT-23-6 package, the UCC28056DBVT simplifies design and reduces board space.
