Hello,

We are going to evaluate a new DC/DC converter to our circuit that already in mass production. And we found ICs that fit to our requirements:

  1. LMR14030

  2. TPS54340  

Our circuit has to pass CISPR 22 class B certification. And I saw, that this particular series aren't having proved to the certification evaluation boards. For us, It will be very helpful if You can give us recommendations or even reference design that can be accepted to Class B limit.

Also, Could You to make simulation of our circuit at your software according to Class B limit? (If yes, could you send me an example of how to prepare circuit for the simulation?)

Best Regards

Oleg Tkachenko
