    Hi Mahesh,

    It sounds like you have already worked out some of the details of the UCC28600 transformer design? If you have not yet worked through the calculations, I would recommend to start by downloading the UCC28600 Design Tool Calculator. TI does not manufacture custom magnetics/transformers/inductors. A quick web search will reveal there are many qualified magnetics vendors that can provide transformer samples from your spec.

    Regards,

    Steve
