UCC38503DWTR TI Power Factor Correction | 20-SOIC | 250kHz, 10V Gate Drive

Product Overview

The UCC38503DWTR from Texas Instruments is a high-performance, average current mode Power Factor Correction (PFC) controller designed for AC-DC power supplies requiring low total harmonic distortion and high power factor. It integrates a boost PFC controller with a 10V gate drive and operates at a fixed frequency of 250kHz. The device is housed in a 20-pin SOIC package, offering a compact solution for medium to high power applications.
