    Hi Felix,

    First, I am assuming that in your power rail chart, "Iout" means RMS/TDC current, and "Max. Iout for IC's" means EDC/peak current.

    I'm not able to access the reference design either, but your choice of TPS53647 & TPS40428 is reasonable based on what I can see. The TPS53647 will require 3 power stages to provide enough current for your application. I would recommend the CSD95410 power stage.

    However, you may be better served by using the TPS53676 in a 3+1 phase configuration to be able to power the 105A VCC rail & the 16A VCCRT rail. The TPS53676 can run two voltage rails off of a single controller, and would allow for a lower total BOM cost. For this application, I would also recommend the CSD95410 power stage. Additionally, the TPS53676 is a newer part than the TPS53647.

    By the way, this thread is currently assigned to is BMC-MCS, the product line which handles the TPS53647, TPS53676, CSD95410, & TPS40428. To get support on the other parts mentioned (TPSM846C24, TPS544C25, TPS549A20, TPS82150), I'd recommend creating a new E2E thread asking about one of them. That will get you in contact with BSR-MV, the product line that handles those parts.

    Thanks,

    Travis
