UCC38503DW TI PFC/PWM Controller | 20-SOIC | 100kHz, 15V/1A Gate Drive

Product Overview

The UCC38503DW from Texas Instruments is a high-performance BiCMOS controller that integrates power factor correction (PFC) and pulse-width modulation (PWM) in a single 20-pin SOIC package. It is designed for offline power supplies requiring high efficiency and low total harmonic distortion (THD). The device operates at a fixed frequency of 100kHz and provides a 15V/1A gate drive output, making it suitable for medium-power applications.
