o0m Introduction Designing for electromagnetic compatibility (EMC) is one of the most difficult challenges for electronic system designers.
Almost all-electronic equipment is required to meet one or more EMC standards at the system or product level.
One of the most challenging subsystems when speaking about EMC is the power supply or in this case the dc/dc power module.
All modern dc/dc converters are composed of one or more switching stages containing both pulsed voltages and currents, which generate a broad noise spectrum resulting in electromagnetic interference (EMI).
This application note will give an overview of electromagnetic interference (EMI), the different standards and regulations, how these standards and regulations relate to dc/dc power modules, suggestions for external filtering solutions, and suggested layout and grounding practices.
The first step in designing systems for EMI compliance is to understand that the different standards and regulations do not directly apply to the dc/dc power module but to the overall system.
Regardless, understanding and minimizing the emissions emanating from the power module is a good beginning to EMI system compliance.

0 General Overview Electromagnetic interference (more commonly known as EMI) refers to how different sets of electronic equipment interact with each other, usually in a negative manner.
The recent advances in semiconductor devices and largescale integration has dramatically reduced the size of electronic equipment while increasing the probability for electromagnetic interference between the different systems and subsystems.
