HOW DOES EMC BECOME A SUCCESS FACTOR FOR YOUR NEXT DESIGN PROJECT?Electromagnetic compatibility (EMC) testing can prove difficult for developers and project managers. In-house testing results are rarely as good as expected, and additional obstacles may arise during development. These unexpected changes can result in shifted schedules, increased development costs, and external post-testing costs. EMC is the ability for electrical equipment to function properly...

SWITCH NODE LAYOUT CONSIDERATIONS FOR EMCThe switch node of a switching regulator or power converter circuit is a critical conduction path that requires special attention when designing the PCB layout. This circuit node is where one or more power semiconductor switches (such as a MOSFET or diode) connect to a magnetic energy-storing device (such as an inductor or transformer winding). The switching signals of this circuit node contain fa...

PCB DESIGN FOR LOW-EMI DC/DC CONVERTERSEvery switch-mode power supply presents a wide-band noise source. Integrating a DC/DC converter from the car board net into an automotive control unit and still fulfilling the EMC requirements of automotive OEMs is a difficult task. Typically, noise from the DC/DC converter and other high-speed circuits radiates via connected cables that provide an effective antenna path. To block this potential ...
