Abstract
A current-mode-control circuit for a switching regulator is provided. The circuit includes a first transistor coupled to a power supply voltage, a second transistor, and an inductor. The circuit further includes a slope compensation generation circuit coupled to the output of the current control circuit through a feedback loop, the slope compensation generation circuit generating a slope compensation current related to the output voltage, an inductor current sensing circuit coupled to the first transistor and the second transistor, and configured to calculate a current through the inductor and output a inductor sense current, and a pulse-width modulation control circuit coupled to the slope generation circuit and the inductor current sense circuit, the pulse-width modulation control circuit receiving the output of the current control circuit, the slope compensation current and the inductor sense current as inputs.
