Hello,
I found a mistake in the diagram of the flyback power supply.
The numbering of the terminals of the transformer Wurth in schematic is wrong.
If it helps designers, here's the good numbers:
5 is bad and 2 is correct.
6 is bad and 1 is correct
8 is bad and 4 is correct
7 is bad and 5 is correct
1 is bad and 6 is correct
4 is bad and 8 is correct
Best regards.
