UCC38503N TI PFC/PWM Controller | 20-PDIP | 250kHz, 15V/1.5A Gate Drive

Product Overview

The UCC38503N from Texas Instruments is a high-performance BiCMOS power factor correction (PFC) and pulse-width modulation (PWM) controller combo IC. It integrates a boost PFC controller and a PWM controller in a single 20-pin PDIP package, designed for offline power supplies requiring high power factor and low harmonic distortion. The device operates at a fixed frequency of 250kHz and provides a 15V/1.5A gate drive output, making it suitable for medium-power applications such as AC-DC adapters, server power supplies, and industrial power systems.
