UCC28503N TI Power Factor Correction | 20-PDIP | 250kHz, 12V/10mA Gate Drive

Product Overview

The UCC28503N from Texas Instruments is a high-performance power factor correction (PFC) controller designed for AC-DC power supplies requiring low total harmonic distortion (THD) and high efficiency. It integrates a boost PFC controller with a PWM controller in a single 20-pin PDIP package, enabling compact and cost-effective designs. The device operates at a fixed frequency of 250kHz and provides a 12V/10mA gate drive output, suitable for driving external MOSFETs. With features like overvoltage protection, brownout protection, and soft start, the UCC28503N ensures reliable operation in demanding applications.
