Abstract
Methods, devices, and integrated circuits are disclosed for providing a buck converter charger in a multiphase buck converter topology comprising at least a first phase, a second phase, and an alternative charging switch, wherein the first phase includes a first high-side switch and a first low-side switch and the second phase includes a second high-side switch and a second low-side switch. The methods, devices, and integrated circuits may control at least one phase to operate as a boost converter, control at least one phase to operate as buck converter, and close the alternative charging switch in the multiphase buck converter topology to connect an alternative charging source to a system voltage output, the alternative charging switch coupled to the first phase between the first high-side switch and the first low-side switch.
