Layout guide for remote voltage sensing for MPM3695-20

Integrated Inductor Power Modules

Hi Support,

Regarding remote voltage sensing and voltage drop compensation for MPM3695-20.

Is there any application note or practical guide for routing VOSNS+ and VOSNS- in remote voltage sensing application? Specifically, what are the recommendations for trace width and spacing between them?

Hello @PC_Peng ,

Apologies for the late response.
It is recommended to do 10mil width and 6mil clearance for the traces.

Also, here are some extra recommendations:

  • Make sure to put the output sense pairs in a quiet signal layer adjacent to solid and quiet GND layers.
  • Avoid routing under or near traces and vias that contain switching signals.

I hope this is helpful.

Regards,
Edgar

Hi Edgar,

Is there any recommendation for spacing between VOSNS+ and VOSNS-?

Hi @PC_Peng ,

Yes, it is recommended 6mil clearance between differential pairs VOSNS+ and VOSNS-.
