Claim:
1. A method, comprising: managing a plurality of hysteretic DC-DC buck converters, each including a hysteretic comparator operating according to a respective hysteresis window, for each of the hysteretic DC-DC buck converters the managing including: verifying if a respective feedback voltage of the hysteretic DC-DC buck converter reaches a lower threshold in order to enter a switch-on period of the hysteretic DC-DC buck converter, detecting if an other hysteretic DC-DC buck converter in said plurality of hysteretic DC-DC buck converters has entered a respective switch-on period, in response to detecting that the other hysteretic DC-DC buck converter in said plurality of hysteretic DC-DC buck converters has entered the respective switch-on period, entering a hysteresis voltage adjustment procedure that includes increasing an amplitude of the hysteresis window of the hysteretic DC-DC buck converter.
