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

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.
