LM25118-Q1: EMI issue

Part Number: LM25118-Q1
Other Parts Discussed in Thread: LM25118

Hi Sir,

My customer is using LM25118 on their system, and facing a EMI issue on 100MHz~200MHz on the inductor area.

Do you have any suggestion to improve the EMI performance?

What I could think about is to add a resistor in serial on the Gate pin of mosfet and the resistor should be within 2~5ohm, do you think this is a good way to try?

Thanks,

Patrick
