SMPS load/voltage variations

SMPS load/voltage variations

SMPS load/voltage variations

(OP)
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?

RE: SMPS load/voltage variations

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.
