UCC28056DBVR TI PFC Controller | SOT-23-6 | 65kHz, 10.5V Startup

Product Overview

The UCC28056DBVR is a high-performance transition-mode Power Factor Correction (PFC) controller from Texas Instruments. It is designed to achieve near-unity power factor and low total harmonic distortion (THD) in AC-DC power supplies. The device operates in critical conduction mode (CrM) with a fixed switching frequency of 65 kHz, enabling compact and efficient designs. Housed in a small SOT-23-6 package, it is ideal for space-constrained applications such as adapters, chargers, and lighting.
