Abstract
In a DC-DC converter, a technique for sensing current supplied to a load and establishing an output voltage that conforms to a predetermined load line. The current carried by an inductor is sensed and used to control the duty cycle of the voltage applied to the inductor, thereby controlling the output voltage. A current sensing circuit includes a feedback network. A pole attributable to the feedback network cancels a zero attributable to the inductor so that a control voltage is developed that varies substantially linearly with the load current.
