    Hi Masazumi-san,

    1. It is possible to design  LLC converter directly from AC line. It might be worth mentioning the power factor will not be as good as if you had a dedicated PFC stage.

    2. The UCC25630x datasheet has a design example for calculating transformer design parameters but it is only for single output. I would need to check if we have any guides or examples with multiple outputs

    3. The image below is one example of how you could configure your transformer windings. 

    Best Regards,

    Ben Lough

    Hello.

    Thank you for your answer.
    Considering the cost, I would like to design with 2 outputs.
    Have you had 2 output user guides and examples of applications?
    Also, is it possible to propose a transformer specification when creating a transformer with 2 outputs?

    thank you.
