Hello to all! Is it possible 85 to 265VAC power supply with 12V 0.5A to build
which at 85 ° C or more, bringing the full power.
Please provide a small, cheap and durable.
What would you recommend for me and which switch transformers?
Ought to be definitely a materials N87, right?
Thank you for your help!

And what is with the 85°C?
You will need to test and find out. There are the obvious measures you can take like uisng a larger device with lower RDSon, provide adequate heatsinking, operate transformer with low KP (highly continuous0, use larger core size to reduce turns to reduce leakage inductance and winding capacitance.
Probably TNY-III series. Use our PI-Expert software design tool to determine appropriate transformer
