I'm reviewing a Gallium Nitrate step-down converter for Point of Load (PoL) high power conversion     This design is intended to deliver low voltage (0.5 - 1.5V) at a power hungry point of load. It can source 50A. With a switching frequency of 600 kHz, the footprint can stay small.     A 48V DC power bus is common in industrial environments. That voltage often needs to be converted to other levels. For high-performance processors, FPGAs and application specific ICs, this ...
