I need a circuit that takes in 3(or less)-40 volts, and puts out 12v at a max current of 550 ma.

What is the cheapest circuit that can do this reliably?
I started with the LT8302 chip to make a fly back, but found its Nps with my voltage range value only allowed me a 1:1 transformer, which I'm thinking is pointless.
I then used TI webench to make circuit in pic related.
Anyone have any better ideas?

ALSO
How do I prototype and build with surface mount chips? Do I need to special order a board with pre printed leads from a software like Eagle?
