Embodiments of a switched-mode power supply and a method for operating a switched-mode power supply involve synchronizing a phase and frequency of an asynchronous controller of the switched-mode power supply with a clock signal of a synchronous controller of the switched-mode power supply while the asynchronous controller is in control of a power stage of the switched-mode power supply, concurrent with synchronizing the phase and frequency of the asynchronous controller with the clock signal of the synchronous controller, presetting a state variable of the synchronous controller while the asynchronous controller is in control of the power stage of the switched-mode power supply, and switching control of the power stage from the asynchronous controller to the synchronous controller after the phase and frequency of the asynchronous controller are synchronized with the clock signal of the synchronous controller and after the state variable of the synchronous controller is preset.
