Optimizing DC/DC Converters for EMI in Automotive Systems

EMI (electromagnetic interference) mitigation is a critical step in the design process in most electronic systems, and especially so in the automotive

EMI (electromagnetic interference) mitigation is a critical step in the design process in most electronic systems, and especially so in the automotive world. In many cases, automotive OEM emissions requirements are even more stringent than both national and international standards bodies like the FCC. Unfortunately, by their nature, switching regulators are sources of EMI; but, in order to keep power supply designs small and efficient, switchers are a critical component. So how can you reap the benefits of a switching regulator while still meeting challenging EMI requirements? In this three-part training series, join Perry as he addresses automotive DC/DC converter EMI mitigation at every step of the design process - from part selection to board layout, filter design, and system debugging - to help you pass the CISPR 25 Class-5 standard with your design.
