UCC29950DR TI AC-DC Controller | 16-SOIC | PFC+LLC, 600V Startup

Product Overview

The UCC29950DR from Texas Instruments is a highly integrated AC-DC controller combining Power Factor Correction (PFC) and LLC resonant half-bridge control in a single 16-SOIC package. It simplifies design, reduces component count, and enhances efficiency for power supplies up to 500W. The device features a 600V startup circuit, advanced burst mode for light-load efficiency, and comprehensive protection features.
