Abstract: An embodiment method executes instructions, each corresponding to switching a signal, a delay, and a condition selected among first, second, or third conditions. Each execution includes performing, after the delay, switching the signal if the condition is the first condition, if the condition is the second condition and a flag is in an active state, or if the condition is the third condition and the flag is in an inactive state, or not switching the signal if the condition is the second condition and the flag is in the inactive state, or if the condition is the third condition and the flag is in the active state. A first instruction represents a first switching of a first signal, a first delay, and the second condition, and is immediately followed by a second instruction representing the first switching of the first signal, a second delay, and the third condition.

Abstract: Contactless power transfer from a transmitter to a receiver is managed. A magnetic field is generated by the transmitter from a command at a control frequency for a switching resonant circuit. The receiver communicates information to the transmitter through modulation of the magnetic field. The modulation is detected by the transmitter so as to extract the information. An adjustment of the control frequency is then made according to the received information. The modulation detection involves detecting variations in the control frequency.

Abstract: In an embodiment a DC to DC conversion circuit includes a DC to DC converter connected to an input path and an output path and a current limiting circuit including a circuit configured to detect when an input or output current of the DC to DC converter exceeds or falls below a current threshold and a controller configured to store a first voltage level of an output voltage of the DC to DC converter in response to the input or output current exceeding the current threshold, to store a second voltage level of the output voltage in response to the input or output current falling below the current threshold and to set a control signal based on the first and second voltage levels.

Abstract: An embodiment DC to DC conversion circuit comprises a DC to DC converter and a regulation circuit. The regulation circuit comprises a comparator configured to detect, during a discharge phase of the DC to DC converter, an overshoot period during which an output voltage of the DC to DC converter exceeds a target voltage, and a timer configured to measure a duration of the overshoot period.
