I got a flyback SMPS with multiple outputs. When I load one of them (+5V), I'm getting voltage increase on others, like 40V from 24V output. Any ideas?
 
Only the main output is regulated, therefore the aux outputs will vary according to load on the main output.If you have the aux outputs with 50% of max load then they should not rise too much above nominal, otherwise you will have to post regulate them.
