What do you know about SMPS?
Are you sure you know enough?
SMPS is dangerous, not recommended for beginners.
Are you a beginner?

If not...
IR2153 is great (and simple).
What part is (can possibly be) unclear for you in that?

I would not get involved with suggesting PetruV dangerous high voltage stuff for his own safety .
This is a free sample of his postings:
