Abstract
A DC/DC converter circuit for phase-modulated communication comprises a push-pull driver to which a reference clock having a fixed predefined frequency can be applied on the input side; a transformer having a primary and secondary coil, wherein the push-pull driver is connected to the primary coil on the output side; a synchronous rectifier connected to the secondary coil on the AC-side; a resonant circuit having a capacitance and an inductance, wherein the resonant circuit is designed such that a part of the resonant circuit is on a primary side of the transformer and another part of the resonant circuit is on a secondary side of the transformer; a decoupling inductor connected on a secondary side of the transformer and downstream of the synchronous rectifier, which is not part of the resonant circuit; and an output capacitor connected in series with the decoupling inductor via which an output voltage is provided.
