    Hello,

    I found this article on the web that compares Semi bridgeless to interleaved PFC.  It used the UCC28061 to accomplish semi-bridgeless.  The UCC38065 has a similar control scheme and should would for this application.

    I do recommend that your read the article however.  There are benefits of interleaving over semi-bridgeless that may have you consider designing for interleaved instead.
