Abstract:
A DC-DC converter includes a current sense circuit. The current sense circuit includes a sense current output, an inductor current measurement circuit, an inductor current emulation circuit, a first switch, and a second switch. The inductor current measurement circuit has an output. The inductor current emulation circuit has an output. The first switch is coupled between the output of the inductor current measurement circuit and the sense current output. The second switch is coupled between the output of the inductor current emulation circuit and the sense current output.
