Tool/software:

Hi support team 

I am using LM5146 evaluation board and measuring CISPR25 conduction current method.
However, it is failing above 30MHz.
Could you please give me some advice on how to overcome this?

Thanks

    Hi Kotaro San,

    A few requests:

    1. Can you share the test setup images with me? 

    2. What is the configuration of the EVM (Input Voltage, Output Voltage, Output Current, Mode Pin, etc.)

    3. Please also share the results that you have captured?

    4. Have you also captured the ambient EMI? (i.e. turn off LM5146EVM and power to it and check the noise floor of the chamberr)? 

    Thanks,

    Best Regards,

    Taru
