    Hi Mike,

    This is your answer to the previous thread I made that was locked before I had a chance to answer - 

    "Hello,

    The following link will bring you to an application note that shows how to extend the Vds range of the UCC24612.

    In the link you mentioned there is no solution for higher VD voltage than 230V of UCC24612.

    I will try again - is there any solution for this kind of problem?

    Thanks.

    Hello,

    I checked the link and it brings you to an application note that shows how to use the UCC24612 and UCC24610 beyond the maximum Vds range.

    This is done with external circuitry that is explained in the application note to reduce the Vds voltage seen by the UCC24612.

    The circuitry in this application note should allow you to use the UCC24612 beyond 230  V.
