Hi,
Perhaps you should take a look at Microchip AN954. May or may not work with that much current. Be careful!

Not switchmode but transformerless.

depending your current requirement, you may find some already built one fore few bucks. i don't think they even need to be design in most case.
Most company have some SMPS controller IC as well. worth to have a look there.

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

some links for me please?
Hello Mister_E,
Would you have one or more links to these components please? I must not search the right way (correct words) since I can't find anything.
By the way, what do you use (what would you use) in this case?
Thank you HenrikOlsson, I read this application note already. Unfortunately, this kind of power supply allows only extremeley narrow min/max power ranges.

How much current do you need?

I need around 0,05mA.
Input voltage is 230VAC 50Hz (Europe).
