Is there a transformer calculation and design tool for LM5022?

Thank you

For Flyback topology.

Hi Jerry,

Thanks for reaching out with your question.

There is not a specific guide line for designing the transformer for the LM5022. Since this is part of the power train of the flyback topology it is very similar for whatever IC is used. Below is a link for an application note that will help with the transformer calculations. It uses the LM3481 but can be applied to any flyback circuit.

Thanks,

Garrett
