TOPswitch flyback with highest feedback loop bandwidth
Posted by: treez

Hi,
Please could you advise of an RDK or an DER document which details the TOPswitch flyback with the highest (or the highest you know of) feedback loop bandwidth?
I would be very grateful if possible.

Thanks, Any power level above 15W.
I just want to see how high the feedback loop bandwidth can be with a TOPswitch flyback, given that it has the internal 7khz pole.
Hi treez,
Good day. What is the power level we are looking at? Our designs are pretty stable and you may check the transient/dynamic responses of each DER or RDK.
To help you also designing the feedback circuit, here are two application notes you can refer to:
