I have used UCD9224 in the past and noticed the Ultrascale reference design uses TPS40428 with CSD95378BQ5MC integrated High/Low side FETs. I would like to have one controller for 3 FPGA voltages (60A@.9V, 15A@1V, 8A@1.2V) but not sure if better to control with device like USCD9224 or do high current with TPS40428 and lower currents with PS544B20 (like reference design). Space and efficiency are key.
Thanks!
