Abstract: A switching regulator may be used to generate an output voltage from an input voltage. The switching regulator includes; an inductor including a first terminal and a second terminal that passes an inductor current from the first terminal to the second terminal, a first switch that applies the input voltage to the first terminal when turned ON, a second switch that applies a ground potential to the first terminal when turned ON, a feedback circuit configured to estimate a load receiving the output voltage, detect when the inductor current reaches an upper bound or a lower bound, and adjust the lower bound based on the estimated load, and a switch driver configured to control the first switch and the second switch, such that the inductor current is between the upper bound and the lower bound in response to at least one feedback signal provided by the feedback circuit.
