Zusammenfassung:	An apparatus, system, and method are disclosed for providing standby power. A switching module adjusts an on-time and an off-time of one or more switches based on a feedback signal. The one or more switches are shared between a primary stage and a standby stage of a switched-mode power supply. A shutoff module interrupts electric power flowing to the primary stage in response to a standby signal having a standby state and allows electric power to flow to the primary stage in response to the standby signal having an on state. A feedback module provides the feedback signal to the switching module. The feedback module bases the feedback signal on an output of the primary stage in response to the standby signal having the on state. The feedback module bases the feedback signal on an output of the standby stage in response to the standby signal having the standby state.
