Abstract
A switching regulator includes a DC-DC converter and a dynamic voltage positioning circuit. The DC-DC converter includes an inductor connected between an input port and an output port. The dynamic voltage positioning circuit includes a sensing circuit and a mirroring circuit. The sensing circuit is configured to sense an inductor current flowing through the inductor, and to convert a voltage applied to a direct current resistance (DCR) of the inductor into a droop current using a variable resistor. The mirroring circuit is configured to cause a voltage drop at the output port of the DC-DC converter based on a current corresponding to a difference between a bias current and the droop current.
