Abstract:
A device and switching method for a circuit for generating an output voltage (Vout) via a control signal (CTRL) with two pulse-width modulated states are described. The control signal (CTRL) frequency (Fq) is measured. In order to generate the control signal (CTRL), either a first hysteresis comparator (31) or a second hysteresis comparator (32) is enabled depending on the control signal (CTRL) measured frequency (Fq). Advantageously, the voltage thresholds of the hysteresis comparators and at least one frequency threshold can be chosen in such a manner as to avoid the control signal (CTRL) frequency (Fq) entering into forbidden frequency bands.
