Hi all,
I have a tny266 flyback converter with two output secondary (4 turns each)....I need to get +5v and -5v ....Here we are taking a feedback with an opto isolator only from +5v ..After building the whole circuit Iam getting +5v and -7v...what would be the problem ??...I turned the transformer perfectly (4 turns each in secondary)....
