UCC2819APW TI Power Factor Correction Controller | 16-TSSOP | 65kHz, 250μA Startup

Product Overview

The UCC2819APW 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 features to achieve near-unity power factor and low total harmonic distortion (THD) in AC-DC power supplies. The device operates with a fixed frequency of 65kHz and features a startup current of only 250μA, making it suitable for energy-efficient designs. Housed in a compact 16-TSSOP package, the UCC2819APW is ideal for space-constrained applications requiring high power density.
