Low EMI and low noise DC/DC conversion in automotive applications

Because of the potential havoc that interference can wreak in radio and safety-critical systems, automotive electronics are subject to the most stringent EMI standards - the most common being CISPR25 Class-5. The materials below provide a discussion around the sources of EMI in an automotive environment and a comprehensive blueprint to understanding how to minimize its effects.
