Two simple questions below:
1. I notice that all this 'SWIFT' series buck converters, have differtial sense of Vo, e.g. TPS546A24, what is the reason for it? Why not use single-end voltage sense like typical buck converter?
2. Why we add PMBus only for high output current 'SWIFT' buck converters? What it the typical load type for PoL, when PMBus is needed?
