    Hello,

    I searched the TI reference design library and found this PMP7167 off line flyback that is close to your design needs using the UCC28610.

    Hello,

    400 Hz is the line frequency generally air craft or ship power.  So you just need a a bridge rectifier which that design has.

    I marked up the schematic to show the AC to DC converter using a bridge rectifier and storage capacitance.  Then you step down the DC voltage to 28V in a DC to DC flyback converter.  I believe the control IC in this design is a UCC28610 and this reference design would work in your application for 50 W.

    On your other post I had recommended using the UCC28711 or UCC28704 and recommended to reference designs as well for the 5 W application.

    Regards,
