Abstract: An adaptive pulse positioning modulator including a sense circuit which provides a compensation signal indicative of output voltage error, a filter circuit having an input receiving the compensation signal and an output providing an adjust signal, a leading ramp circuit which provides a repetitive first leading edge ramp signal having a slope which is adjusted by the adjust signal, a comparator circuit which provides a first start trigger signal when the first leading edge ramp signal reaches the compensation signal and a first end trigger signal when a first trailing edge ramp signal reaches the compensation signal, a trailing ramp circuit which initiates ramping of the first trailing edge ramp signal when the first start trigger signal is provided, and a pulse control logic which asserts pulses on a PWM signal based on the trigger signals.

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.
