Abstract: Disclosed examples include integrated circuits configurable according to sensed circuit conditions to provide configurable power converter topologies with externally connected circuitry to implement buck, boost, buck-boost, low dropout and/or hot-swap power converters. The ICs include one or more sets of series connected high and low side transistors connected with corresponding IC pads to allow connection to external circuitry to form a particular power converter configuration. The IC includes a control circuit and a configuration circuit to sense a circuit condition of the IC and to configure the control circuit to provide switching control signals to the transistors to implement one of a plurality of power converter topologies.

Abstract: From at least a first microphone, first microphone signals are received that represent first sound waves. From at least a second microphone, second microphone signals are received that represent second sound waves. In response to the first microphone signals, first noise in the first sound waves is estimated, and first cancellation signals are output for causing a speaker array to generate first additional sound waves via at least a first acoustic beam for cancelling at least some of the first noise. In response to the second microphone signals, second noise in the second sound waves is estimated, and second cancellation signals are output for causing the speaker array to generate second additional sound waves via at least a second acoustic beam for cancelling at least some of the second noise.
