Other Parts Discussed in Thread: LM5146-Q1
I checked EMI filter in LM5146-Q1 datasheet and the one implemented in LM5146-Q1-EVM12V board with CISPR25-C5 requirements (around 63dBuV)
Can you confirm two pi stages (the one for diff mode and the second for common mode?)
For the second stage, the 33uF polarized doesn't respect the Cd > 4*Cin.
Globally, could you give explanations with this EMI filter please?
Thank you for your help
