A switched-mode power supply (SMPS) device is for converting a voltage to another voltage by using a switching action. A high-speed switching operation has multiple problems as well as advantages. The present invention relates to an SMPS device, and more specifically, to an SMPS device which minimizes the occurrence of derived frequencies even in the case of load variations and voltage variations to stably operate at a unique frequency. As means to realize the above-described embodiment, the present invention includes an oscillator for generating a voltage gradient waveform in accordance with time, a comparator, and the SMPS device which uses an output of the comparator as a driving power source for a modulator or the oscillator or induces a mixed wave to enable a stable operation. |
