    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



    Schematic :-

    If ST says it will work, it will work.
    That is if you can get the TX wound correctly.
    If not...KAPUUUUT. PFFFFFT with SMOKE... or my favorite BAAAAANG !

    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.
