Optimizing DC/DC Converters for EMI in Automotive systems

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 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?

Practical Comparisons of 3 different DC-DC Control Modes

Certain end-equipment, like communications, server, industrial, and personal electronics have design challenges solved by the DC/DC converter’s control-mode.  This session will compare and contrast 3 different devices using 3 different control modes under the same design criteria to see how each control mode solves particular size, efficiency, external component, ripple and transient response design challenges.
