Voltage regulator and method of controlling a voltage regulator comprising a variable inductor

摘要: Disclosed herein are embodiments of an improved switching regulator and a method for controlling regulator, example, to meet stringent transient demand high efficiency requirements over wide operating range without impacting system stability. According one embodiment, the may be voltage comprising plurality phases, each phase power stage operable produce output load, driver coupled driving based on modulated input signal supplied stage. A variable inductor is included within stages in order load conditions set points. controller signals compensate changing filter characteristics when inductance inductors changes with current.
