Abstract
A hybrid power converter circuit includes a switched-capacitor power converter stage and a pulse-width modulation (PWM) or resonant output circuit coupled to a switching node of the switched-capacitor power converter stage. In particular, the PWM or resonant output circuit can include a transformer having a primary winding and a secondary winding magnetically coupled to each other, and the secondary winding is coupled to the output node of the power converter. The switched-capacitor power converter stage is coupled between the input node of the power converter and the primary winding of the transformer, and includes capacitors and switches configured to connect the capacitors to the input node during a first phase of operation and connect the capacitors to the primary winding of the transformer of the PWM or resonant output circuit during a second phase of operation.
