Fairchild AN-4151SC Application Note
The document provides an overview of the AN-4151SC LLC resonant converter, explaining its principle of operation, the role of the resonant tank, and the benefits of using an LLC topology for high‑efficiency power conversion. It also outlines the typical circuit topology, including the rectifier, resonant tank, and filter components.
Further sections discuss practical design issues such as integrated transformer design, selection of operating mode for maximum gain, and specific features of the FSFR product series. A reference design example with a 400 VDC input and 24 V/192 W output is presented, along with performance graphs and guidelines for achieving zero‑voltage‑switching (ZVS) operation. This manual is written in Japanese.
