UCC3817N TI Power Factor Correction Controller | 16-PDIP | 0-95% Duty Cycle, 6V UVLO

Product Overview

The UCC3817N from Texas Instruments is a high-performance power factor correction (PFC) controller designed for boost converters operating in continuous conduction mode (CCM). It integrates advanced control features to achieve near-unity power factor and low total harmonic distortion (THD). Housed in a 16-pin PDIP package, this controller is ideal for medium-power AC-DC applications requiring compliance with IEC 61000-3-2 harmonic standards.
