UCC38050DR TI Power Factor Correction Controller | 8-SOIC | 18V Supply, 1.5A Gate Drive

Product Overview

The UCC38050DR from Texas Instruments is a high-performance power factor correction (PFC) controller designed for AC-DC power supplies. It operates in transition mode (TM) with a fixed-frequency option, enabling efficient power factor correction up to 0.99. The device integrates a 1.5A gate driver, low startup current (50µA), and comprehensive protection features including overvoltage, undervoltage lockout, and overcurrent protection. Housed in an 8-pin SOIC package, it is ideal for compact power supply designs.
