Abstract: A converter includes an inductor configured to receive an input signal and output configured to supply an electrical load with an output signal. The converter operates to charge the inductor until a maximum pre-set current value is reached during a first operating condition in which the electrical load is not supplied. Next, the converter actively supplies the electrical load by partially discharging the inductor during a first time interval of a second operating condition. Then, the converter passively supplies the electrical load by the residual charge of the inductor during a second time interval, subsequent to the first time interval, of the second operating condition, by discharging the inductor completely.

Abstract: A control apparatus of an engine ignition spark plug includes a switch having a control terminal and an output terminal connected to an external transformer. The switch assumes a closed state for supplying energy to the transformer, and an open state for the transformer to supply energy to the spark plug. A measuring module measures a time duration where, in the open state, a voltage at the output terminal of the switch decreases from a first value to a second value. A detecting module detects an operating condition of the spark plug based on comparing the measured time duration to a time threshold, and to generate a detecting signal based on the comparing.

Abstract: A control circuit of a voice coil motor is configured to move at least one read/write head of an hard disk into a parking position. The control circuit compares a received supply signal with a reference signal having a minimum value and a maximum value and a frequency.

Abstract: In a multi-phase power supply voltage regulator functioning at a nominal switching frequency, one or more phases are kept off for optimizing energy efficiency at relatively low load conditions. Reactivation of stand-by phases in response to a load increase transient is made more efficiently by exploiting information already present in the output voltage control loop. The technique comprises a) deriving from the control loop information on the equivalent nominal switching frequency given by the product of the nominal switching frequency by the number of active phases; b) updating at every beat of a clock signal the instantaneous value of the equivalent switching frequency; c) determining the band of equivalent switching frequency values to which the instantaneous value belongs; d) logically combining the equivalent switching frequency information with a determined band of output current level, for switching on one or more stand-by phases in response to a load increase transient.
