I've been working on a sepic converter. There are some great parts
out there in tiny packages.
Then, for example, I find the fets need a square inch of 2oz copper
(to achieve 78C/W), to get the heat out. And the diodes, and the sense
resistors, and ... A square inch, I can fit another 4 inductors in
that space.
What is the point of making parts that small? I'm looking at a TO220
fet now because it needs less pcb space than a superSOT-6 device.
