Abstract
A resonance-based DC-DC converter for converting a DC input voltage to a first DC output voltage (VOUT1) on a output conductor (9) includes an inductor (L) having a first terminal connected to a source (2) of a DC input voltage (VIN) and a second terminal coupled to a first conductor (4) and a capacitor (CRES) having a first terminal coupled to the first conductor. A first switch (SW1) is coupled between the resonance conductor and the output conductor to conduct inductor current (IL) into the output conductor during a first phase (Phase1). A second switch (SW2) is coupled between a second terminal of the capacitor and the output conductor to conduct inductor current through the capacitor into the output conductor (9) during a second phase (Phase2). A third switch (SW3) is coupled between the second terminal (31) 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 (VIN) during a third phase (Phase3).
