Tool/software:

Hi, 

I am using LMR51450SDRRR for converting 24V to 5V DC. I am facing some issues in Conducted Emissions Test. We are border line in the limits and would like to make it better. Any suggestions will be much appreciated. Please refer to the schematics below for the components used:

L1 is a Ferrite Chip ,600Ohm @ 100MHz.

Thank you.

    Hi Samrat, 

    Thank you for your question. This application report can provide some key insight into improving conducted EMI results. 

    If you would still like more assistance after following the best practices outlined in the application note in optimizing your EMI filter, please send your layout to review. Following the best layout practices as outlined in the datasheet in section 9.3 is critical to good EMI performance.

    Thank you,

    Joshua Austria
