International Rectifier IRIS40xx Application Note
The document provides a detailed guide for engineers designing flyback transformers used with the IRIS40xx series SMPS ICs. It defines required power‑supply parameters such as input voltage, output power, minimum frequency and maximum duty cycle before proceeding to calculations.
Key topics include transformer design methodology, selection of magnetic core types, wire‑gauge tables, winding ratio calculations, and a list of recommended component suppliers. Safety and creepage requirements are also addressed, with references to UL1950 and EN60950 standards. This manual is written in Chinese.
Covers: Introduction to Flyback Transformer Design · Power Supply Design Standards · Transformer Design Steps · Transformer Structure · Magnetic Core Types · Wire Gauge Table
