Hi Abdelrhaffar,

Thanks for using the e2e forum.

We have several resources available for LM5022 design.
All relevant equations should be within the LM5022 datasheet in the Application and Implementation chapter.

Which topology does this design use?

For general calculations, I highly recommend the power stage designer tool:

For Flyback application, we have an additional calculator excel sheet:

Please let me know if you need additional resources.

Best regards,
Niklas
