Hello Sho,

Sorry for the delayed response.

SV601132B_Source_Final EVMs.zip I have attached here are the layout files for the LM5160 Fly-Buck EVM which you can use as reference for your design. For a 5W application, please ensure that the Transformer you are using has very low leakage inductance (<1%) as this will considerably affect your secondary(isolated output voltage)

Please let us know if you have more questions.

Regards,

Sourav
