Hi,
I'm still looking if we have the data, but in the meanwhile, I found a test report with radiated and conducted emissions for a circuit that utilizes the LMR16030. You may look into it and see if it helps you in your design.

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?
Best regards,

Hi,
Yes you can find more information in regards to layers and design in here
http://www.ti.com/tool/PMP15013
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.…
DIVYA KM,
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…
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
