Abstract: Embodiments of a power supply are disclosed that include a first voltage converter having a first feedback controller and a first regulated output, and second voltage converter having a second feedback controller and a second regulated output electrically coupled to the first regulated output. The power limit of the first voltage converter is lower than the power limit of the second voltage converter, and a reference voltage for the first feedback controller is higher than the reference voltage for the second feedback controller.
