Abstract
A step-down DC converter configured to smooth ripple voltage. The step-down DC converter includes a ripple-filtering inductor, a power isolating and converting unit, a power switch, a first capacitor, a second capacitor, a first rectifying switch, a second rectifying switch, and a first inductor. The power isolating and converting unit includes a plurality of windings for separating the step-down-DC converter into an input stage and an output stage. The power switch and the first capacitor are arranged at the input stage, and the first capacitor is connected to the power switch. The second capacitor, the first rectifying switch, the rectifying switch, and the first inductor are arranged at the output stage, the second capacitor is connected to one terminal of the first inductor, and the other terminal of the first inductor is connected to the first rectifying switch and the second rectifying switch.
