UCC28511N TI PFC/PWM Controller | 20-PDIP | 100kHz, 10V Gate Drive

Product Overview

The UCC28511N 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 a boost PFC controller and a PWM controller in a single 20-pin PDIP package, enabling compact and efficient AC-DC converters. The device operates at a fixed frequency of 100kHz and provides a 10V gate drive output for external MOSFETs. With features like overvoltage protection, undervoltage lockout, and soft start, the UCC28511N ensures reliable operation in demanding applications.
