Compare, analyze, and simulate two popular 48V VRMs: STC and linear-extendable-group-operated point-of-load (LEGO-PoL) converter;
Achieve soft start-up for STC using optimal-trajectory-control (OTC) and eliminate the current imbalance problem of LEGO-PoL;
Build switching loss model to evaluate the performance of two converters.
