One app note tells you to clear the ground plane below the switch node and inductor on your DC-DC converter layout. Another one tell you that you definitely shouldn’t do that. Which one is right?!

In this new YouTube video, we take a look at some custom made circuit boards, designed to help answer this exact question.

The video covers:

  • Comparison of 4 DC-DC layouts
  • Near-field scans using the Scanphone
  • Near-field scans using the EMSCAN EHX-83
  • Radiated emissions test using TekBox biconical antenna
  • Reduction of ambient noise in an office environment
