Abstract: A power management system that can include an application processor and a power management unit (PMU). The PMU can generate a regulated output voltage based on control signals generated by a switch control module of the application processor. The control signals can be determined based on a comparison of monitored voltages within the application processor and a generated reference voltage. The reference voltage can be generated based on fed back signals corresponding to the control signals. The application processor and the PMU can be formed utilizing different size manufacturing process technologies. For example, the PMU can be formed utilizing a larger size manufacturing process technology than the application processor.

Abstract: A single-wire interface of an application processor that communicates with another single-wire interface of a power management unit (PMU) via a control signal line. The control signal line can be a single signal path. Further, the single-wire interfaces can communicate with each other only via the control signal line. The single-wire interfaces can be utilized for the communication of pulse width modulation (PWM) control signals, current sensing, and Zero-I detection.

Abstract: A hysteretic switching regulator with low output ripple voltage is disclosed herein. A detector and controller is specifically used to adjust a parameter of the hysteretic switching regulator to compensate for changes in one or more of input voltage and desired output voltage to maintain the output ripple voltage within some desired range.

Abstract: A circuit includes a switching regulator that produces a first voltage supply output and that includes an operational supply input. The operational supply input may provide power for running the logic in the switching regulator. The circuit also includes a linear regulator that produces a second voltage supply output. A control circuit accepts the first voltage supply output and the second voltage supply output and includes a power output connected to the operational supply input. The control circuit is configured to pass the second voltage supply output to the power output until the first voltage supply output is established. After the first voltage supply is established, the control circuit instead passes the first voltage supply output to the power output through the control circuit. The first voltage supply output may also then provide power to the circuitry that would otherwise have been powered by the linear regulator.
