Abstract
A resonance-based DC-DC converter for converting a DC input voltage to a first DC output voltage (V) on a output conductor () includes an inductor (L) having a first terminal connected to a source () of a DC input voltage (V) and a second terminal coupled to a first conductor () and a capacitor (C) having a first terminal coupled to the first conductor. A first switch (SW) is coupled between the resonance conductor and the output conductor to conduct inductor current (I) into the output conductor during a first phase (Phase). A second switch (SW) is coupled between a second terminal of the capacitor and the output conductor to conduct inductor current through the capacitor into the output conductor () during a second phase (Phase). A third switch (SW) is coupled between the second terminal () of the capacitor and a first reference voltage (GND) to conduct inductor current from a source of the first reference voltage through the capacitor to the input voltage (V) during a third phase (Phase).
