UCC3818DTR TI Power Factor Correction Controller | 16-SOIC | 0.5A Gate Drive, 6V UVLO

Product Overview

The UCC3818DTR from Texas Instruments is a high-performance, average current mode Power Factor Correction (PFC) controller designed for 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 0.5A gate driver, undervoltage lockout (UVLO), overvoltage protection, and a 1.5% accurate voltage reference. Housed in a compact 16-SOIC package, it is ideal for AC-DC power supplies requiring high efficiency and compliance with harmonic standards.
