Hello everyone,

I would like to use LM5045 for my design. I have found that AN-2222 should contain reference design of 720W powerful converter, but I'm not able to download mentioned schematic, AN and design files. It looks that links are not valid anymore..... Could you please help? Where to access those files? Many thanks.

    Hi Josef,

    It looks like the design was withdrawn from the web.

    I can remember that this design cannot maintain regulation at lower input voltages, close to 36V, due to the turns ratio of the transformer. The transformer is a planar design and the number of turns in quantised in coarse steps.

    Also the design is expensive to build so it was not popular.

    I can send you the files by email which you are welcome to use as a basis for your design but you will need to invest some time to do your own due diligence in the design.

    Regards

    Peter
