Ventilation and heat manage about inn3378,inn3678, and lnk6665,6667
I`m the student developer who purchased LNK6665,LNK6667 and consider buying inn3378and 3678.
I don`t really want to fry my PCB for my sloppy design, So I have to ask here first.
My product will have 40x40mm ventilation hole. And I use Open Frame while I use Pi experiments. Will 50x5mm heatsink be enough to cool the LNK6665?
And Do I have to put heatsinks on INN3378 and 3678 when they are on the same PCB? Is putting heatsinks on INN3378 and 3678 useless?
