UCC28050DR TI PFC Controller | 8-SOIC | 18V Supply, 1.5A Gate Drive

Product Overview

The UCC28050DR from Texas Instruments is a high-performance, fixed-frequency, pulse-width modulation (PWM) controller designed for power factor correction (PFC) boost converters. It operates in continuous conduction mode (CCM) and provides near-unity power factor with low total harmonic distortion (THD). The device integrates a 1.5A gate driver, undervoltage lockout (UVLO), overvoltage protection, and a 1.5% accurate voltage reference. Housed in an 8-pin SOIC package, it is ideal for AC-DC power supplies requiring high efficiency and compliance with harmonic emission standards.
