EMC Compliant Layouts for DC-DC Converters

The technical literature provides hardware developers with all manner of useful tips regarding the design of switching controllers. From the selection of the appropriate power inductor, input/output capacitors, MOSFETs, and Schottky diodes, application examples ranging all the way to a specimen PCB layout are presented that demonstrate how an EMC-compliant design can be realized. Virtually every state-of-the-art PCB contains one or several DC/DC converters in one form or another. This is why before/after comparative EMC measurements of discretely integrated DC/DC converters give almost all hardware developers an interesting opportunity to deepen his/her knowledge in this area.
