UCC2818APWR TI Power Factor Correction Controller | 16-TSSOP | 250kHz, 12V

Product Overview

The UCC2818APWR from Texas Instruments is a high-performance, average current mode Power Factor Correction (PFC) controller designed for boost converters. It operates at a fixed frequency of 250kHz and provides near-unity power factor with low harmonic distortion. The device is housed in a compact 16-TSSOP package, making it suitable for space-constrained applications. With a wide input voltage range and robust protection features, the UCC2818APWR is ideal for AC-DC power supplies requiring high efficiency and compliance with IEC 61000-3-2 harmonic standards.
