Abstract
In one embodiment the present invention includes a DC to DC converter device which includes an electronic circuit. The electronic circuit comprises a first comparator, a second comparator, a first switch, a first latch, and a current sensor. The inductor current includes a peak current value and a valley current value. The first comparator detects the peak current value and resets the first latch which opens the first switch. The second comparator detects the valley current value and sets the first latch which closes the first switch. The current sensor is coupled to sense an inductor current flowing through an output load, and is coupled to provide a sense voltage to the first and second comparators. In this manner, the electronic circuit provides DC to DC conversion with current control.
