Hello, it seems this IC creates very strong emissions anywhere from 30MHz to 300MHz. It can be very broadband as well. I thought it was originally our design implementation, but I've just ordered an evaluation board and it seems this board is very noisy as well. Please review screen shots attached. I'm wondering if there's anything we can add to the design to reduce or remove these emissions.
We've also seen the emission on the eval board from TI, which should have the best ideal layout , correct?
We finally changed the gate driver resistors from 0 ohm resistors to 39ohm resistors, we powered it up and the IC, MOSFETS, and Inductor proceeded to get extremely hot. The current on our supply was then current limited and the IC or Mosfets then blew up and our board turned off. We are still figuring out what to do next.. Essentially this caused a huge current surge for some reason.
