TPS54331: EMC Issue support needed

Part Number: TPS54331

Hi team,

The customer now has an oven project using tps54331 as the DCDC module, but during the EMC test, the vertical radiation can not pass at 10Mhz, can you provide some analysis direction and specific rectification measures?

The details are as follows

1. The customer now has an oven project that uses tps54331 as a DCDC module to plug vertically on the main control board, as shown in the following figure:


2. The schematic diagram of the tps54331 module is as follows:


3. The customer's current project is in the late stage, so it is not allowed to make great changes to the schematic diagram and layout, but it is allowed to add a little small component to the schematic diagram or modify the parameter value of the component.

Thanks!

Best Regards
