Switch Mode Power Supplies and their Magnetics

Focus:

A two-page application note presents an overview on magnetic components used in switched-mode power supplies (SMPSs). It explains the purpose of the output transformers, output inductors, input inductors, and current-sense transformers in SMPS applications and provides basic guidance on selecting core materials and shapes for these components based on factors such as power supply topology, switching frequency, current levels, and space requirements.

What you’ll learn:

• How to understand the roles of magnetic components in switched-mode power supplies
• How to select inductor and transformer cores for switched-mode power supplies (overview)
