    Very nice work!

    Is a single sided pcb sufficient from an EMI perspective?

    This SMPS includes Under voltage protection using LM311 Chip thats why its there.

    There is Over current protection into this *Basic* SMPS design, The seperate board for the LM311 + The protection circuit, was to save some space, as ludo suggested!
