TPS40170: Using Faster FETs results in gate drive oscillations.

Part Number: TPS40170

Hello,

I have a question reguarding the ringing issue and the first ringing spike solution with snubber circuits,

when i am using the component for high voltage buck converting (around 35-50 volts input, and 7-8 volts output) what should be the optimal design solution for the ringing issue?

what is the recommanded Cin and Cout in this kind of circuit?

what is the recommanded design for the required voltage output of 7.5v / 6A?

  • Victor. I'll close this and carry on with your other post.

    See WEBENCH for design recommendations. You can access it from the TPS40170 product page. It's on the right-hand side.
