Abstract
A drive control circuit generates switching drive signals for a single phase of a multiphase voltage regulator. A driver circuitry generates the switching drive signals for the voltage regulator responsive to a clock signal. A clock circuitry generates the clock signal responsive to a monitored external clock signal. A phase number detector determines a number of active phases in the multiphase voltage regulator in real time responsive to an indicator on a phase number input monitored by the phase detector.
