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.
