Trade-offs When Selecting Automotive Dc/Dc Converters

Posted on 05 November 2019

      In automotive designs using dc/dc converters, strict conducted and radiated emissions have to be met. Emissions in the Radio LW, MW, SW and FM bands are more tightly controlled to avoid interfering with the vehicle’s radio reception, Figure 1. By Dan Tooth, Texas Instruments The most tightly controlled being the FM band, [...]
