I have a requirement of Dual Output supply.
  • Output 1 :- 17V , 400mA
  • Output 2 :- 3.3V , 1A
  • Isolate supply

I found eDesign suite on ST's website which gives reference design upon filling the requirement.

I have attached the schematic, parameters and other info.
I just want to confirm the reliability/completeness/accuracy of this design

A very elaborate solution for such simple needs.
1 to 17 V? A wall transformer, op amp, pot and power transistor.
3.3 V? 5 V 1 Amp wall transformer (phone) with a 3.3 V regulator.
