PMP9656: EMI issue

Llin Ronnie

Part Number: PMP9656

Hi Team,

We followed the ref design and built the board according to the suggested BOM, but the EMI test was failed at conductive mode.

Could you please provide the solutions?  Thanks!

Best regards,

Ronnie Lin

    Hi Ronnie,

    This reference design only demonstrates the DC-DC power conversion.  EMI is tested at the system level of a design.  You will need to add some input filtering for EMI compliance.  How the filtering is configured will be dependent on what EMI requirements you are required to meet, and how your system is configured as a whole. 

    thanks,

    Brian
