Other Parts Discussed in Thread: CSD17312Q5, CSD17309Q3
I'm using an LM27403 controller in a 12V-->3p3v application. As the Lm27403 is the only part on the board with via-in-pad I want to move the thermal vias out of the pad onto the board to avoid epoxy fill or taping the vias in production.my layout looks like this:
the stitching vias on the ground poly sink into a board-wide ground plane. This should be more than adequate electrically, but am concerned about thermal issues.
Is there any guidance that you can provide in this regard?
thanks
