摘要： A control circuit for a DC/DC converter has a linear-control loop, which receives a quantity to be controlled and a first reference quantity, and generates a modulation value. A nonlinear modulation unit is activated in presence of a variation of the quantity to be controlled higher than a preset intervention threshold and modifies in a nonlinear way the reference quantity supplied to the linear-control loop. In the case of large variation and of preset sign of the quantity to be controlled, the linear-control loop is deactivated, a signal for switching-off of the DC/DC converter is initially generated, and then a false steady-state-modulation value is supplied to the DC/DC converter.

摘要： Peak current in a switching converter is controlled using a closed loop to compensate for error caused by delay time in the switching transistor and control logic. A reference value is established that represents a target current value. A compensated reference value is derived from the reference value by the closed loop. A periodic inductor current is formed in the switching converter in response to the compensated reference value. An error signal is formed that is indicative of an amount of time the inductor current exceeds the target current value. The compensated reference value is dynamically adjusted by the compensation closed loop to minimize the error signal.

摘要： The protection circuit includes a reference voltage source and at least one circuit which are connected together via a switch. A memory element is connected to the input of the circuit, downstream of the switch. The switch is temporarily opened by a control signal generated by a monostable circuit when detecting switching of power elements belonging to an electronic device embedding the protection circuit. When the switch is open, the memory element supplies the circuit with the reference voltage previously stored. In this way, switching of the power element that might cause noise on the reference voltage cannot disturb the circuit and thereby cannot cause a faulty operation of the latter.
