UCC3818APW TI Power Factor Correction Controller | 16-TSSOP | 0.5A Gate Drive, 6V UVLO

Product Overview

The UCC3818APW is a high-performance power factor correction (PFC) controller from Texas Instruments, designed for boost PFC applications. It operates in continuous conduction mode (CCM) with average current control, providing near-unity power factor and low total harmonic distortion (THD). The device integrates a 0.5A gate driver, undervoltage lockout (UVLO), and overvoltage protection, making it suitable for a wide range of AC-DC power supplies.
