We made one power supply by using Top 266EG, its not take desiged power,ckt diagram made by power int sftware only.


No of outputs 15V,3A ; 5V , 1A; 15V,1A

I/p range 85-265AC 




Logesh - 


I don't understand your question.  Can you please explain in more detail what problems you're having?  Can you also attach your PI Expert design files?

By using power int software  we designed power supply for 15V,3A; 5V,1A  and 5v, 1A. its having 3 outputs...


v got the output voltage as we designed.but its not taking load. means voltage getting dip.


can u tell me what are the changes need to be done....or which part i need to concentrate.


otherwise send some application note for 15V,3A; 5V,1A  and 5v, 1A.(isolated) outputs. 


pls do the needful 




This isn't enough information to help with your questions.  


Can you please send me the following:

- the files from your PI Expert design

- A PDF of your PCB layout

- A PDF of your circuit schematic (if it is significantly different than shown in PI expert)

- Some better information about what conditions cuase the poor load regulation.
