Yes you can find more information in regards to layers and design in here
it is a 4 layer board.
The small grey holes around the trace is to have a ground stitching and provide some shielding for the trace. Yes it is…
Thank you for your answer!
We think this is good for our customer.
We understand that It is important not only IC but also layout about CISPR.
Do you have any information about CISPR 24?
From the .TSC file you attached, you'll need:
A catch/freewheeling diode from GND to SW.
Probably more capacitance on VIN.
Probably more capacitance on VOUT.
Take a look at this reference design PMP15013 for general guidelines (see the…
I think you have to use a combination of LC filter as well as CMC as precaution.
The LC filter is to cut down the fundamental switching noise where as the CMC is to cut down the higher frequency one.
Here is one sample design
