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 [1] input filter design tool
 * Real examples of EMI testing in the chamber using the LM73605 [2] and
   LM76003 [3] evaluation boards
