Abstract:
A resonant tank circuit for a DC-to-DC converter includes a resonant inductor having a first terminal connected to a switching node of a half-bridge switching circuit. The resonant inductor has a second terminal connected to resonant tank circuit output node. A first capacitor has a first terminal connected to a voltage reference and has a second terminal connected to a capacitor branch node. A second capacitor has a first terminal connected to the capacitor branch node and has a second terminal connected to the resonant tank output node. A first diode has an anode connected to the voltage reference and has a cathode connected to the capacitor branch node. A second diode has an anode connected to the capacitor branch node and has a cathode connected to a voltage rail.
