Hi Team,
My customer is using LM5008 and face EMI issue, he thought it might be caused by ring in SW node. Base on his experience to add a quite small cap. between drain and source of MOSFET can improve this issue. Since SW and VIN node is close, that is easy to rework as well. Customer wants to know how large capacitance he can try and that will not affect the LM5008's operation.
Thanks very much.
