Hello Carlo,
for this low power range a standard flyback will make it; have a look at PMP7958 or PMP10200, both HV designs. Controllers like LM5021/5022 are suited, but QR controller like UCC287k-series will offer improved over all efficiency and better light…
Hi Darren,
There is guidance for applications> 100V in LM5034 datasheet.
Besides, you can refer to below LM5022 reference designs for detail circuit.

PY,
Unfortunately to change this design to 600V input would require significant changes. This includes the transformer, power MOSFET and clamp circuit. PMP7958 and PMP5067 can be referenced, though they are for higher power. You can also use TI's Power…
Other Parts Discussed in Thread: PMP20745 , PMP9334 Dears:
There is a demand as follows:
1. DC-DC input is 18v~380v, output is 12V or 5V
2. Iout is 1.5A or 2A above.
I found the solution from reference design.
And from the PMP20745 datasheet I can see…
The LM5022 also lists several wide input range designs:

This one is close at 30-300 V:

This regulates on the primary bias rail, but…
