Abstract: In an example, a dual-phase inverting buck-boost power converter for use with at least first and second energy storage elements includes an inverting buck-boost power converter and an inverting boost converter. In an example, the inverting buck-boost power converter is coupled between an input node and an output node of the dual-phase inverting buck-boost power converter and includes a first plurality of switches operable to couple to the first energy storage element, wherein the inverting buck-boost power converter is operable to supply a first load current. In an example, the inverting boost converter is coupled in parallel with the inverting buck-boost power converter between the input node and the output node of the dual-phase inverting buck-boost power converter and includes a second plurality of switches operable to couple to the first and the second energy storage elements, wherein the inverting boost converter is operable to supply a second load current.

Abstract: A circuit includes a binary weighted divider having a first set of switches coupled in series between an input node and a feedback node. The first set of switches is configured to set a feedback voltage at the feedback node in response to activating or deactivating respective switches in the first set of switches. A set of compensation switches is coupled to the first set of switches. The set of compensation switches is configured to reduce resistance of one or more of the respective switches in the first set of switches that are activated by activating one or more switches in the set of compensation switches to provide one or more respective parallel current paths for each of the switches in the first set of switches that are activated.

Abstract: A circuit includes a signal generator to generate an output signal to vary the switching frequency of a switching circuit to mitigate noise in the switching circuit. The signal generator includes a modulation waveform generator (MWG) to generate a ramp signal in response to a numerical input and a switching signal from the switching circuit. The ramp signal is employed to modulate the frequency of the output signal of the signal generator over a range of frequencies from a minimum frequency to a maximum frequency. A frequency adjuster circuit modulates the amplitude of the ramp signal by adjusting at least one of the minimum frequency or the maximum frequency of the range of frequencies.
