Reconfigurable multiphase power stage for pulsed chargers

There are methods, devices and integrated circuits for a buck converter charger disclosed in a multi-phase buck converter topology, comprising at least a first phase, a second phase and a switch for alternative shop, the first phase of a first high-side switch and a first Low -Side-switch and the second phase comprising a second high-side switch and a second low-side switch. The methods, devices and integrated circuits can at least control a phase so that it operates as a boost converter, at least control a phase so that it operates as a step-down converter, and close the switch for alternative malls multiphase buck converter topology to an alternative charge source to connect a system power output, the switch being coupled for alternative charging between the first high-side switch and the first low-side switch with the first phase.
