Abstract: Features and advantages of certain embodiments include a plurality of power supplies that work together to deliver power to a target circuit. In one embodiment, a downstream power supply provides a fast current delivery in response to load current transients and generates a feedback signal to control an upstream power supply so that the upstream and downstream power supplies work together to meet the current and voltage requirements of a target circuit across a wide range of loading conditions.

Abstract: Features and advantages of the present disclosure include a switching regulator and current measurement circuit. In one embodiment, a switching transistor in the switching regulator has a first voltage on a first terminal and a switching voltage on a second terminal. A current measurement circuit has first and second input terminals. A first switch couples the second terminal of the switching transistor to the first terminal of the current measurement circuit when the switching transistor is on, where the second input terminal of the current measurement circuit is coupled to the first terminal of the switching transistor and measurement(s) may be taken. When the switching transistor is off, the first and second input terminals of the current measurement circuit are coupled together, and measurements emulate zero current through the switching transistor.

Abstract: A method and system for managing electrical current within a portable computing device (“PCD”) includes assigning a priority to two or more communications supported by the PCD. A present level of a power supply for the PCD may be monitored by a communications power (“CP”) manager module. Next, the CP manager module may determine if the two or more communications may be transmitted at the present level of the power supply. If the two or more communications cannot be transmitted at the present level of the power supply, then the CP manager module may determine if a timing of at least one of the communications may be adjusted. The CP manager module may also determine a theoretical power level adjustment for at least one of the communications. The two or more communications may be transmitted with any calculated timing off sets and power level adjustments.

Abstract: A voltage regulator circuit using precharge voltage rails is generally disclosed. For example, the voltage regulator circuit may include a first voltage regulator having a voltage output, an output capacitor coupled to the voltage output, and one or more precharge voltage circuits configured to selectively couple to the voltage output, each of the one or more precharge voltage circuits comprising a capacitor coupled between an output of a precharge voltage regulator and a reference potential.

Abstract: Methods and apparatuses can implement voltage regulation with frequency control. In an example aspect, a voltage generator includes an output node and a switch. A voltage controller is coupled to the switch of the voltage generator. A mode controller is coupled to the voltage controller. The voltage controller is configured to control an output voltage at the output node by closing and opening the switch at a switching frequency. The voltage controller is configured to operate in multiple operational modes. The mode controller is configured to cause the voltage controller to shift between two or more operational modes responsive to the switching frequency. The switching frequency can be moved out of a rejection frequency band by shifting operational modes. Shifting can include, for example, shifting from a PFM mode to a PWM mode or shifting from one hysteresis mode to another hysteresis mode within the PFM mode.

Abstract: Disclosed is a voltage regulator circuit configured to selectively operate the voltage regulator circuit in a first mode of operation and a second mode of operation. The voltage regulator can change operation of the voltage regulator circuit between the first mode of operation to the second mode of operation in response to a change in a sensed load condition of the voltage regulator circuit. The voltage regulator can change operation from the second mode of operation to the first mode of operation in response to the sensed load condition changing from the second load condition to the first load condition, but only when the sensed load condition has not changed in a given direction between the first load condition and the second load condition for at least a predetermined period of time T.

Abstract: System, methods, and apparatus are described that facilitate signaling between devices over a single bi-directional line. In an example, the apparatus couples a first device to a second device via a single bi-directional line, indicates initiation of a first action, initiated at the first device, by sending a first single transition on the single bi-directional line from the first device to the second device, and indicates initiation of a second action, initiated at the second device, by sending a second single transition on the single bi-directional line from the second device to the first device. In another example, a first device initiates a first action, indicates initiation of the first action by generating a first event on a single bi-directional line, and receives an indication of a second action initiated at a second device by observing a second event on the single bi-directional line.
