Can you send me the design procedure you use for the UCC287xx Buck? To modify the value of the components and be able to obtain the power I require.

    Hello,

     

    The UCC287xx was design for PSR flyback controllers and all the released design collateral is for flyback controllers. 

     

    I discussed this design with an engineer that has done this design before and there is a little bit of trial and error involved.   I have attached their design procedure for your reference.

     

    Thank you for interest in Texas Instruments (TI) products.  If you have a related question, please click the "Ask a related question" button in the top right corner. The newly created question will be automatically linked to this question.
