ADP1621 SEPIC Design

     We are planning on using the ADP1621 and the AD5292 to create a digitally controllable voltage regulator circuit that can output 1.215V to 26.3V up to 2A, the problem is we are limited with the fsw because of the bandwidth of the AD5292 and we cannot use the SEPIC Design tool because it doesn't let us configure the fsw. The datasheet has a computation but it is for boost configuration, can we use that for our SEPIC design? If possible can you give us the computation for component selection for the ADP1621 for SEPIC?
