Abstract
A circuit and method for a switching converter that modifies the clock frequency when the panic comparator is activated is proposed. This solution for a switching converter is achieved by increases in the switching frequency in response to an undershoot condition. In summary, a switching converter circuit, comprising at least one phase functional block configured to provide an output voltage, a panic comparator configured to evaluate voltage excursion conditions of the output voltage, and a clock generator with pulse insertion function wherein the pulse insertion function is configured to increase the switching frequency during a voltage excursion condition to minimize or mitigate voltage excursions. In addition, a switching converter circuit, comprising a clock generator with a pulse width extender configured to provide a signal to said pulse insertion function logic.
