A single-stage regulator that directly converts a battery voltage to a microprocessor core voltage can be designed when high voltage drivers are employed. Multiphase power conversion is a marked departure from earlier single phase converter configurations previously employed to satisfy the ever increasing current demands of modern microprocessors. Multi-phase converters, by distributing the power and load current, result in smaller and lower cost transistors with fewer input and output capacitors. These reductions accrue from...
