With regard to undesirable interactions, what are the considerations when locating two separate inductors in a SEPIC with one above the other on the top and bottom of the PCB?
eg, should you use inductors with the same/different winding directions etc..
(I know you can get dual/coupled inductors in one package but I don't want to limit myself to a 'specialized' inductor.)
I think the answer is that they should always be the same winding direction, but just wanted to check.
Flipping one upside-down for bottom layer shouldn't change anything from a winding direction standpoint.
