UCC28500N TI Power Factor Correction | 20-PDIP | 250W, 85-265VAC

Product Overview

The UCC28500N from Texas Instruments is a highly integrated power factor correction (PFC) and pulse width modulation (PWM) controller designed for offline power supplies. It combines a boost PFC controller and a PWM controller in a single 20-pin PDIP package, enabling compact and efficient power supply designs. The device operates from a wide input voltage range of 85V to 265V AC and supports output power levels up to 250W. With advanced features such as average current mode control, soft-start, and overvoltage protection, the UCC28500N simplifies the design of high-performance AC-DC converters.
