UCC28051DR TI PFC Controller | 8-SOIC | 8.5V-18V, 65kHz

Product Overview

The UCC28051DR from Texas Instruments is a high-performance, fixed-frequency, average current-mode boost power factor correction (PFC) controller. It operates in continuous conduction mode (CCM) and is designed to achieve near-unity power factor and low total harmonic distortion (THD) in AC-DC power supplies. The device integrates a 1.5A gate driver, overvoltage protection, and a low startup current of 50µA. Housed in an 8-SOIC package, it is ideal for applications requiring compact size and high efficiency.
