I have one problem in my project.
My power supply when start with load the output is 25V and I remove the load and the voltage stay in 25V.
If I start the power supply with no load conected the power supply output is 38V and when I put the load stay in the 38V.
What is my problem?
The Bias Waveform amplitude is 32V?

This is a current driver
I do not understand your circuit. Could you please explain me a little bit about the way it operates. I am talking about the feedback circuit. I see three sensing resistors, R6, R9 and R11. But I do not see how are you sensing the output current.
I see the inverting input of your op-amp. It is connected to a fixed voltage of 2.5 through the voltage divided made by R1 and R12. The non-inverting input is connected to the return node.
I am very confused. Please explain me how it works
Thank you
I have problem with the AC-DC converter using TOP260YN, the source does not turn to put load is removed the load it usually triggers.

Hi,
Following the discussion that replied by Worf, are you saying there is a new issue? Would you please give a little bit more information that I can further support you?
I am sorry, I do not really understand "the source does not turn to put load is removed the load it usually triggers."

Could you please post your schematic?
Thank you
