UCC2819ADR TI Power Factor Correction Controller | 16-SOIC | 250W, 10-21V

Product Overview

The UCC2819ADR from Texas Instruments is a high-performance power factor correction (PFC) controller designed for AC-DC power supplies. It operates in transition mode (TM) and is optimized for medium-power applications up to 250W. The device integrates advanced features to achieve high power factor (>0.99) and low total harmonic distortion (THD). Housed in a compact 16-SOIC package, it is ideal for space-constrained designs.
