UCC28503DW TI PFC/PWM Controller | 20-SOIC | 250W, 100-240VAC

Product Overview

The UCC28503DW from Texas Instruments is a highly integrated, dual-mode power factor correction (PFC) and pulse-width modulation (PWM) controller designed for medium-power AC-DC applications. It combines a boost PFC controller and a forward PWM controller in a single 20-SOIC package, simplifying design and reducing component count. The device operates from a wide input voltage range of 100V to 240V AC and delivers up to 250W of output power. With advanced features such as valley switching, frequency dithering, and comprehensive protection, the UCC28503DW is ideal for power supplies requiring high efficiency and reliability.
