    ASICs, FPGAs, and processors in high-performance communication, servers, and computing systems require core power supplies that can produce voltages of 1.0 V (or less) directly from a 12 V or intermediate bus—with maximum load currents sometimes above 200 A. These supplies must meet stringent efficiency and pe

    Datasheets are often long and cumbersome, meaning locating and interpreting the required information is not always trivial. Furthermore, the meaning of the listed parameters is rarely explained in the datasheets, and even the slight differences in how they are interpreted can be critical for how a device behaves in
