Abstract: An amplifier stage of an LDO regulator circuit includes an amplifier stage that generates a drive signal in response to a first voltage difference an output voltage of the LDO regulator circuit and a reference voltage. A drive stage having a quiescent current consumption is configured to generate a control signal in response to the drive signal. The control signal is applied to the control terminal of a power transistor. A dropout detector senses whether the LDO regulator circuit is operating in closed loop regulation mode or in open loop dropout mode by sensing a second difference in voltage between the drive signal and the control signal. A quiescent current limiter circuit responds to the sensed second difference by controlling the quiescent current consumption of the drive stage, and in particular limiting current consumption when the LDO regulator circuit is operating in the open loop dropout mode.

Abstract: A DC-DC converter circuit including at least: a first step down converter having a first pair of switching devices in a half bridge configuration. A second step down converter includes a second pair of switching devices in a half bridge configuration. The first and second step down converters are connected in parallel to an output node connected to an output coil and receive command signals. A feedback loop includes a synchronization module receiving the gate control signals of high side switching devices and adjusts as a function of the gate control signals a delay in a signal path from the command signal to each gate control signal of the high side switching device to synchronize the gate control signals.

Abstract: A device includes a master device, a set of slave devices and a bus. The master device is configured to transmit first messages carrying a set of operation data message portions indicative of operations for implementation by slave devices of the set of slave devices, and second messages addressed to slave devices in the set of slave devices. The second messages convey identifiers identifying respective ones of the slave devices to which the second messages are addressed requesting respective reactions towards the master device within respective expected reaction intervals. The slave devices are configured to receive the first messages transmitted from the master device, read respective operation data message portions in the set of operation data message portions, implement respective operations as a function of the respective operation data message portions read, and receive the second messages transmitted from the master device.

Abstract: Several first digital streams of first digital samples at a first sampling frequency are processed to issue corresponding stream that are converted into second digital streams sampled at a second sampling frequency lower than said first sampling frequency. At least one delay to be applied to at least one first digital stream to satisfy a condition on the second digital streams is determined and applied to at least one first digital stream before converting. The converting operation performed is decimation filtering of the first digital streams. The application of the at least one delay to at least one first steam involves skipping a number of first digital samples in the at least one first digital stream. The number skipped depends on the value of the at least one delay. Samples that are skipped are not delivered for decimation filtering.

Abstract: A voltage regulator includes an input terminal to receive an input voltage, an output terminal to supply an output voltage, a power transistor, a differential amplifier, a driver, a dropout detector and a bias current limiter. The differential amplifier provides a drive signal based on a difference between a voltage reference and a feedback signal corresponding to the output voltage. The driver includes an impedance device, and a driver transistor that receives the drive signal so as to vary a bias current to a control terminal of the power transistor. The dropout detector and the bias current limiter is coupled to the input terminal, the impedance device, and the output terminal and includes first and second transistors coupled together, and a bias current generator coupled to the second transistor.

Abstract: The reversal of the flow of output current in a voltage regulator is prevented by equipping the voltage regulator of a regulation transistor controlled by an analog voltage control, having its current terminals connected between the control terminal of the fifth transistor power of the regulator and the power supply line or the common ground node of the regulator. The regulation transistor is configured to provide an electrical path of conduction between the control terminal and the power supply line or the ground node and is controlled by an analog voltage control that varies in a continuous manner between a first level, suitable to extinguish the regulation transistor, and a second level suitable for biasing it in an operating condition of deep conduction, as the difference between the supply voltage and the regulated output voltage approaching an offset voltage.
