Patent attributes
A power converter includes a first conversion circuit coupled to a first port, a second conversion circuit coupled to a second port, and a driver. The first conversion circuit has a first flying-capacitor coupled to a first network of switches, and two inductors both coupled to the second conversion circuit. The second conversion circuit has a second flying-capacitor coupled to a second network of switches. The driver drives the first and the second network of switches with a sequence of states having at least one of a first phase and a second phase. When the power converter operates as a step-down converter, the first phase charges the second flying-capacitor and the second phase discharges the second flying-capacitor. When the power converter operates as a step-up converter, the first phase discharges the second flying-capacitor and the second phase charges the second flying-capacitor.
