Abstract
A system and method are provided for controlling a modified buck converter circuit. A pull-up switching mechanism that is coupled to an upstream terminal of an inductor within a modified buck converter circuit is enabled. A load current at the output of the modified buck regulator circuit is measured. A capacitor current associated with a capacitor that is coupled to a downstream terminal of the inductor is continuously sensed and the pull-up switching mechanism is disabled when the capacitor current is greater than a sum of the load current and an enabling current value.
