UC3872N TI Resonant Controller | 14-PDIP | 1MHz, 5V-20V

Product Overview

The UC3872N from Texas Instruments is a high-performance resonant-mode controller IC designed for zero-voltage switching (ZVS) and zero-current switching (ZCS) applications. It integrates all necessary functions for controlling resonant converters, including a voltage-controlled oscillator (VCO), error amplifier, and protection features. Housed in a 14-pin PDIP package, it operates over a wide supply voltage range of 5V to 20V and supports switching frequencies up to 1MHz. The device is ideal for high-efficiency power supplies, DC-DC converters, and resonant inverters.
