UCC3819N TI Power Factor Correction Controller | 16-PDIP | 0-95% Duty Cycle, 12V/10mA

Product Overview

The UCC3819N from Texas Instruments is a high-performance power factor correction (PFC) controller designed for AC-DC power supplies. It operates in continuous conduction mode (CCM) with average current control, enabling near-unity power factor and low harmonic distortion. Housed in a 16-pin PDIP package, this controller is ideal for applications requiring high efficiency and compliance with IEC 61000-3-2 standards.
