Abstract: The present invention relates to a voltage converter based on a switching regulator, and more particularly, to systems, devices and methods of dynamically controlling an output of the voltage converter to rapidly transition between different power supply voltages as required in many electronic devices. The switching regulator generates an output supply voltage that tracks a voltage originally provided by an internal DAC. During the supply voltage variation, a step control signal is provided to introduce a supplemental voltage step into the reference voltage before the reference voltage is used to generate the output supply voltage. The switching regulator is thereby overdriven under this supplemental voltage step, enhancing the slew rate and the settling time of the output supply voltage to meet stringent requirements imposed by many electronic devices.

Abstract: Various embodiments of the invention provide extend the switching frequency range of DC/DC multiphase switching regulators in order to overcome prior art frequency limitations in the number of available phases, for example, in low input to output ratio applications. In certain embodiments, this is accomplished by enabling partial overlap between multiple phases using asynchronous logic. The invention is easily scalable without introducing significant silicon area penalties.
