UC3855ADWTR TI Power Factor Correction IC | 20-SOIC | 500kHz, 250W

Product Overview

The UC3855ADWTR is a high-performance power factor correction (PFC) controller from Texas Instruments, designed for offline power supplies requiring near-unity power factor and low total harmonic distortion (THD). It integrates advanced average current mode control and operates at frequencies up to 500kHz, enabling compact magnetic designs. The device is housed in a 20-pin SOIC package and is ideal for applications such as 5G base stations, server power supplies, and industrial systems.
