UC3864N TI PWM Controller | 16-PDIP | Resonant Mode, 1MHz

Product Overview

The UC3864N from Texas Instruments is a high-performance resonant mode PWM controller designed for off-line and DC-to-DC power supply applications. It integrates all necessary functions for zero-voltage switching (ZVS) and zero-current switching (ZCS) topologies, enabling high efficiency and reduced electromagnetic interference (EMI). Housed in a 16-pin PDIP package, this controller operates at frequencies up to 1 MHz, making it suitable for compact, high-density power designs.
