SYSTEMS AND METHODS FOR SWITCHED-INDUCTOR INTEGRATED VOLTAGE REGULATORS
First Claim
1. A power controller, comprising:
- an output terminal having an output voltage;
at least one clock generator to generate a plurality of clock signals;
a plurality of hardware phases, each hardware phase being coupled to the at least one clock generator and the output terminal and including a comparator, each hardware phase being configured to;
receive a corresponding one of the plurality of clock signals and a reference voltage;
combine the corresponding clock signal and the reference voltage to produce a reference input;
generate a feedback voltage based on the output voltage;
compare the reference input and the feedback voltage using the comparator; and
provide a comparator output to the output terminal, whereby the comparator output determines a duty cycle of the power controller.

Abstract
Power controller includes an output terminal having an output voltage, at least one clock generator to generate a plurality of clock signals and a plurality of hardware phases. Each hardware phase is coupled to the at least one clock generator and the output terminal and includes a comparator. Each hardware phase is configured to receive a corresponding one of the plurality of clock signals and a reference voltage, combine the corresponding clock signal and the reference voltage to produce a reference input, generate a feedback voltage based on the output voltage, compare the reference input and the feedback voltage using the comparator and provide a comparator output to the output terminal, whereby the comparator output determines a duty cycle of the power controller. An integrated circuit including the power controller is also provided.
