UCC38501DW TI PFC/PWM Controller | 20-SOIC | 100kHz, 15V/0.5A Gate Drive

Product Overview

The UCC38501DW from Texas Instruments is a high-performance BiCMOS power factor correction (PFC) and pulse-width modulation (PWM) controller designed for offline power supplies. It integrates a PFC stage and a PWM stage in a single 20-pin SOIC package, enabling compact and efficient power conversion. The device operates at a fixed frequency of 100kHz and provides a 15V/0.5A gate drive output, making it suitable for medium-power applications such as AC-DC adapters, server power supplies, and industrial power systems.
