Abstract
In accordance with an embodiment, a method of controlling a switched-mode power supply includes operating the switched-mode power supply in a first operating mode by monitoring a feedback signal from an output of the power supply using a feedback interface circuit in a first configuration. The method further includes determining when the feedback signal crosses a first threshold in a first direction, and transitioning the switched-mode power from the first operating to a second operating mode by switching the feedback interface circuit from the first configuration to a second configuration.
