Abstract
A voltage regulator includes an input connectable to a voltage source and an output connectable to a load. The voltage regulator includes an inductor coupled to the output, a switch between the input and the inductor, and a current control loop configured to control the duty cycle of the switch to regulate voltage at the output, wherein the duty cycle being based on both a peak and valley threshold level of current flowing through the inductor.
