摘要： A control circuit for a voltage source generates a reference signal for a voltage source, wherein the reference signal indicates a requested output voltage to be generated by the voltage source. A digital feed-forward control circuit computes a digital feed-forward regulation value indicative of a requested output voltage by determining a maximum voltage drop at strings of solid-state light sources. A digital feed-back control circuit determines a minimum voltage drop for current regulators/limiters for the strings and determines a digital feed-back correction value as a function of the minimum voltage drop. The control circuit then sets the reference signal after a start-up as a function of the digital feed-forward regulation value and corrects the reference signal as a function of the digital feed-back correction value.

摘要： In an embodiment a processing system includes a sub-circuit including a three-state driver circuit, wherein the three-state driver circuit has a combinational logic circuit configured to monitor logic levels of a first signal and a second signal, and selectively activate one of the following switching states as a function of the logic levels of the first signal and the second signal: in a first switching state, connect the transmission terminal to the positive supply terminal by closing the first electronic switch, in a second switching state, connect the transmission terminal to the negative supply terminal by closing the second electronic switch, and in a third switching state, put the transmission terminal in a high-impedance state by opening the first electronic switch and the second electronic switch.

摘要： 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.
