UC3871N TI Phase Shift Resonant Controller | 18-PDIP | 1MHz, 10.5V-20V

Product Overview

The UC3871N from Texas Instruments is a high-performance phase shift resonant controller designed for zero voltage switching (ZVS) full-bridge converters. It integrates all control functions required for efficient power conversion in a compact 18-pin PDIP package. Operating at frequencies up to 1MHz, it enables high power density designs with reduced switching losses. The device features programmable dead time, soft-start, and synchronization capability, making it ideal for telecom, server, and industrial power supplies.
