    Hi John,

    We have now developed an LLC power supply (input 395V; output 24V 300W) using the OnSemi FSFR2100 controller and Magnetica transformer 1860.0160.
    The OnSemi FSFR2100 is now EOL, and we need to redesign with a different controller with minimal changes.
    I used TI WEBENCH, which suggests using the UCC256601 controller, but it does not recommend any ready-made transformers.
    TI has an EVA board UCC25660EVM-064, but its output is only 12V, and we need 24V.
    Is it possible to modify this board to achieve a 24V output, or do you have another EVA board with the UCC256601 that has a 24V output?
    Can I use that Magnetica transformer with UCC256601 controller?
    Or, what would be your recommendation for achieving the best result?

    Hi Pertti,

    PMP23463 is really close to what you are looking for. This could be your best starting point. 

    I hope this answers your question.

    Hi Pertti,

    Our reference designs are not normally available for sale, but we do provide everything you need to start you own design. Do you have a local sales contact who can help you?
