Where can I find more info on Flyback converter feedback circuits.
I am using TOP switch IC to design a flyback converter. But want to learn more about the feedback ckts used.

I am already using PIExpert. I would like to learn more about the different types of feedback circuits. Any books, webpages?

Hi,
The different types of feedback are: primary zener, secondary zener, simple resistor, zener-opto, TL431-opto.

In the PIExpert software, on the left hand side, check for a part called Feedback components. Double click that, and then you can see the different types of feedback circuits, the different components and configuration.

Tahmid, I already looked at those app notes.
Powerint website doesn't have much on feedback ckts.
I am aware of the different types of feedback topologies. But I want to learn more about them. Why one is better than the other etc.
Thanks anyway.
