UCC38050P TI Power Factor Correction Controller | 8-PDIP | 18V Supply, 1.5A Gate Drive

Product Overview

The UCC38050P from Texas Instruments is a high-performance power factor correction (PFC) controller designed for AC-DC power supplies. It operates in critical conduction mode (CrCM) to achieve near-unity power factor and low total harmonic distortion (THD). The device integrates a 1.5A gate driver, under-voltage lockout (UVLO), over-voltage protection (OVP), and a voltage reference, making it suitable for compact and efficient PFC stages. Housed in an 8-pin PDIP package, it offers a cost-effective solution for medium-power applications up to 300W.
