Abstract: An apparatus is disclosed for a switch-mode power supply with a network of flying capacitors and switches. In an example aspect, the apparatus includes a switch-mode power supply with an inductor, a switching circuit, and a network of flying capacitors and switches. The switching circuit is coupled to the inductor. The network of flying capacitors and switches is coupled to the switching circuit and includes at least two flying capacitors and multiple switches. The multiple switches are configured to selectively connect the at least two flying capacitors in parallel between a first terminal of the network of flying capacitors and switches and a second terminal of the network of flying capacitors and switches or connect the at least two flying capacitors in series between the first terminal and the second terminal.

Abstract: Aspects of the present disclosure generally relate to methods and apparatus for continuous current sensing for a single-inductor multiple-output (SIMO) regulator. One example method includes operating a plurality of switches of the SIMO regulator, via a plurality of control signals, according to a plurality of switching states using a switching controller, sensing currents associated with at least a portion of the plurality of switches of the SIMO regulator using a plurality of current sense circuits, and selectively outputting a sense current from one of the plurality of current sense circuits based on a change in the plurality of controls signals occurring between a transition from a first switching state to a second switching state of the plurality of switching states.

Abstract: Methods and apparatus for operating a switched-mode power supply (SMPS). One example method generally includes comparing a signal representative of an amount of current across an inductive element of the SMPS with at least three thresholds, selecting a configuration of the SMPS based on the comparison, and configuring the SMPS based on the selection.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for operating a switched-mode power supply (SMPS). One example method generally includes selecting a first output of a plurality of outputs of the SMPS based on a power demand associated with each of the plurality of outputs if a voltage at the first output is less than a reference voltage associated with the first output, by selecting as the first output one of the plurality of outputs having the highest power demand, and based on an amount of overcharge associated with the first output if the voltage at the first output is greater than the reference voltage, by selecting as the first output one of the plurality of outputs having the lowest amount of overcharge. The method may also include directing current across an inductive element of the SMPS to the first output based on the selection.

Abstract: A switching power converter includes a converter input configured to receive a first electrical signal, and a converter output configured to supply a second electrical signal at a desired voltage. The switching power also converter includes a control circuit for controlling one or more switches to produce the desired voltage. The control circuit is configured to control the one or more switches using one of pulse-frequency modulation and pulse-width modulation, such that an oscillating signal is generated using a combination of random frequency-hopping and random phase-chopping.

Abstract: A method of generating spurious-noise-free power from a switching device. The method includes generating an oscillating signal in the form of a series of pulse trains, and randomly changing the switching frequency, or the on-time, or both the switching frequency and the on-time of the switching device. The method further includes causing the switching device to change from a first frequency to a second frequency only at the end of a pulse train of the first frequency, and causing the second frequency to start at the beginning of its first pulse train such that no switching duty-cycle disturbance at the time of the change from first to second frequency. In a particular embodiment, the method further generates spurious-noise-free power from a switching device by implementing a relationship between the different switching frequencies involved such that spurious-noise-free operation is achieved.
