UCC28501N TI PFC/PWM Controller | 20-PDIP | 100kHz, 10.5V UVLO

Product Overview

The UCC28501N from Texas Instruments is a high-performance combined Power Factor Correction (PFC) and Pulse Width Modulation (PWM) controller designed for offline power supplies. It integrates both PFC and PWM stages in a single 20-pin PDIP package, simplifying design and reducing component count. The device operates at a fixed frequency of 100kHz and features a programmable soft-start, overvoltage protection, and under-voltage lockout (UVLO) with hysteresis. It is ideal for AC-DC converters requiring high efficiency and low harmonic distortion.
