    Abstract: An inductor current detecting circuit is provided. A current supplying circuit supplies a first current signal to an energy storage circuit having a zero voltage during a high-side conduction time, and a second current signal to the energy storage circuit having the zero voltage during a low-side conduction time. A voltage comparator circuit subtracts a valley voltage of a low-side switch from a peak voltage of a high-side switch to obtain a reference voltage, and outputs a comparison signal according to a voltage of the energy storage circuit and a reference voltage. A current modulation controller circuit modulates currents of the first and second current signals according to the comparison signal. A synthesizing circuit synthesizes the first and the second current signals, each of which charges the voltage of the energy storage circuit to be equal to the reference voltage from zero, to obtain an inductor current signal.
