    Hello Feeney, 

    According to this application note: https://www.ti.com/lit/pdf/sluaa28 only the controller IC needs to be replaced, no other changes are needed.
    The switching frequency will stay the same. 

    However, if your customer wishes to take advantage of higher frequency capability, then the boost inductors must be redesigned, and other components changed as per the app-note to support it.  

    Regards,
    Ulrich
