Abstract: An inductor current reconstruction circuit for use in switched-mode power supply, as well as a reconstruction method thereof are disclosed. In reconstruction circuit, an inductor current sampling circuit is employed to detect current through switch transistor during on-time and thereby output sampled voltage, and a slope of sampled voltage is compared with a voltage slope of a reconstructed signal. If the two are unequal, the generator circuit is adjusted so that the voltage slope of reconstructed signal becomes equal to that of sampled voltage. The voltage of reconstructed signal can characterize the waveform of an inductor current. This reconstruction circuit allows signal reconstruction to be extended from one on-time of switch transistors, whichever is longer, to the other on-time, thereby achieving inductor current reconstruction over each entire period. The inductor current reconstruction circuit provided is particularly suitable for use in applications with a relatively large or small duty cycle.
