    Hi Danny,

    Thanks for reaching out. I checked the BOM but unfortunately I could not find information about the transformer information either. 

    For active clamping flyback you normally want to run it at DCM. So you may choose one with less inductance compared to ordinary CCM operating with passive clamping. 

    If you still have question about the transformer parameter, please let me know the input voltage, output voltage & current, and switching frequency. Let me know if you want to do passive clamping flyback which is more common in PoE application. 

    Best regards,

    Diang
