UCC28514N TI PFC/PWM Controller | 20-PDIP | 250kHz, 10.5V-15V

Product Overview

The UCC28514N 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 250kHz and features a wide input voltage range of 10.5V to 15V. With advanced protection features and low startup current, the UCC28514N is ideal for applications requiring high power density and reliability.
