TPSM863257: Are the via´s needed in the not connected SW pad ?

Part Number: TPSM863257

The Datasheet is showing thermal via´s also for the not connected SW pad.

Do we need them as heatpipes ?

Can we remove them ?

Do we need to add extra copper on different layer ?

Hi Peter,

Thanks for reaching out. How about I share you EVM PCB gerber files so that it can help you understand how to place vias and extra copper?

Thanks!

Hi Lucia ,

I would appriciate it if I could get these , but I wonder if the via´s are actually necessary for thermal reason. I have limited space available and any via I can avoid would help ;) , I also want to avoid causing unnecessary extra EMI.

Kind regards

Peter

Hi Peter,

Please let me check internally. Meanwhile, I will first send you the gerber file by email.

Thanks!

Hi Peter,

Actually vias are necessary and can help on thermal dissipation.

Any further concern, feel free to let me know. Thanks!
