    Hello Mark,

    The LM5026 does not have ant integrated OVP function so if you wish to use this part you will need to design in an external OVP circuit.
    The UCC2897A has an integrated LINEOV function that shuts down the controller in the event of an overvoltage.

    The UCC2897AEVM board has almost the same design specifications as the LM5026EVAL board.

    The EVM is located here:

    I believe the UCC2897A is probably a better solution to your requirements than the LM5026
