UCC2819AD TI Power Factor Correction Controller | 16-SOIC | 250kHz, 10V-21V

Product Overview

The UCC2819AD from Texas Instruments is a high-performance power factor correction (PFC) controller designed for AC-DC power supplies. It operates in continuous conduction mode (CCM) with a programmable switching frequency up to 250kHz. The device integrates advanced features such as overvoltage protection, brownout protection, and a low startup current of 100µA. Housed in a compact 16-SOIC package, it is ideal for space-constrained applications requiring high efficiency and low total harmonic distortion (THD).
