Reducing EMI via considerations external to the IC

If your device has switching elements, it's going to emit EMI. Learn how to minimize it through external component selection and layout.

For many engineers, layout for EMI mitigation is a black art. It may seem like the slightest adjustment could be the difference between passing or failing CISPR standards. Because of this, some power designers may shy away from using devices with switching elements as a guaranteed way to avoid the headache of reducing emissions. But this may be trading one problem for another, as switching devices generally have better efficiency and thermal performance. That's why we created this training series- we want you to be able to get the best of both worlds: solid efficiency and thermal performance without having to worry about emissions.

This training series will dive into the many approaches to solving the emissions problems raised through the use of devices with internal switching elements. Pi filters, ferrite beads, loop sizes, you name it - it's all here in one place.
