    Hi Kevin! 

    Thanks for getting in touch! Generally we recommend either the LM5045 or the UCC28250 for hard-switching full bridge converters. The LM5045 device is better suited for primary side controlled applications while the UCC28250 / UCC28251 are better suited for secondary side controlled applications. 

    Thanks again for reaching out, I hope this information helps!
