Hi, I designed a LED driver with PIExpert and I bought the transformer from RTS; this circuit works fine, but when I tried to make the transformer for my self it doesn´t works; it´s appears that doesn´t maintain output voltage while input voltage varies with constant load; I use same materials as sample´s transformer (I disassemble your transformer and reuse copper foil and ferrite core), but it doesn´t works too.
Can you give me some help please?
I send attached result of design from PIExpert.
Thanks for your response.
