Hi Guido,

Thanks for using the e2e forum.

Is isolation required for this application?
In this case, you could use a isolated flyback topology, using LM5155.

Thanks and best regards,
Niklas

Yes, Isolation is required to generate +/-24V. Is there a Reference Design ?

Hi Guido,

Here is a reference design for a PSR flyback design with positive and negative outputs.
If customer needs just one output rail, they can simplify the design.
