UC2855BDW TI Power Factor Correction Controller | 20-SOIC | 12V/500mA Gate Drive

Product Overview

The UC2855BDW is a high-performance power factor correction (PFC) controller from Texas Instruments, designed for AC-DC power supplies requiring near-unity power factor and low total harmonic distortion (THD). Housed in a 20-pin SOIC package, this device integrates advanced control algorithms to achieve efficient and reliable operation in continuous conduction mode (CCM) boost converters. It features a 12V/500mA gate drive output, making it suitable for driving external MOSFETs in medium-power applications.
