Hi Team,
Our customer would like to build an isolated power supply that would operate from a universal AC input and outputs at 85V/7A. He is considering flyback or LLC, however, we don't have reference designs that fit his requirements. According to our customer,
I do need an alternate for my trade study. I do like the LLC solution, and I don't see any higher power reference designs (nothing as high as 200 Watts even). Would there me an interleaved Flyback or Interleaved Forward option to look at? A bridge would be a comparison I could use although it is so close to the LLC that there's not a lot of difference in cost probably. Is there a reason that the UCC28056 is not recommended for power above 300 Watts?
Regards,
Danilo
