UC3879N TI Phase Shift Resonant Controller | 20-PDIP | 0-1MHz, 10.5-20V

Product Overview

The UC3879N 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 20-pin PDIP package. Operating from 10.5V to 20V supply, it provides precise phase shift control up to 1MHz, enabling high-density power supplies with reduced switching losses.
