Mitigation of switching regulator EMI (electromagnetic interference) is sometimes referred to by engineers as black magic, as designers often struggle to meet stringent EMI requirements when creating a power supply system. These challenges can easily lead to redesigns, which can then potentially lead to schedule delays and cost overruns. In this thorough technical training, Marc addresses those challenges presented by EMI design and provides tips on how to avoid them before you even heat up your soldering iron. Some of the key topics covered in this training are the following:

• What is EMI and where does it come from?
• Optimizing layout for EMI using the datasheet
• Examining the impact of an input filter on conducted emissions, featuring the WEBENCH input filter design tool
• Real examples of EMI testing in the chamber using the LM73605 and LM76003 evaluation boards
