Hi,

EMI data is mentioned in the datasheet as follows.

My customer would like to know also radiation EMI data from 0.15~1000MHz.

And, could you tell me the load current value on this measurement condition?

Hi,

The conducted emmision were made with our standard EVM, the output is 5V @5A, Vin is 12.0V. You can refer to the User's Guide SNVU522 for the full test report.

Hi Terry-san,

Thank you for your support.

I recognizing that the data on SNVU522 is "conducted" noise.
Could you provide "interfered(RE)" noise data with dithering?

Kuramochi,

I have never measured the radiated emmissions on the LM5141 EVM.
