MPQ2908 48V BUCK CONVERTER FOR AUTOMOTIVE REFERENCE DESIGN

New automotive designs are adopting 48V power systems in order to reduce power loss in the vehicle’s cable harnesses and reduce their weight. However, this presents a challenge when trying to comply with EMC regulations. Success is possible through thoughtful component placement and PCB layout, together with techniques like frequency spread-spectrum (FSS). This reference design showcases a ...
