UCC28528DW TI PFC/PWM Controller | 20-SOIC | 100-240VAC, 250W

Product Overview

The UCC28528DW from Texas Instruments is a highly integrated, dual-mode power factor correction (PFC) and pulse-width modulation (PWM) controller designed for offline power supplies. It combines a boost PFC controller and a forward PWM controller in a single 20-pin SOIC package, enabling compact and efficient AC-DC converters. The device operates from a wide input voltage range of 100V to 240V AC and supports output power levels up to 250W. With advanced features such as valley switching, frequency dithering, and comprehensive protection, the UCC28528DW simplifies design while meeting stringent energy efficiency standards.
