An apparatus, system, and method is provided for reducing idle power in a
power supply. The apparatus includes a connection module to determine
whether a load is connected to the output terminal of the power supply.
Also included is an idle module that turns off the power supply for an
idle interval when the connection module determines that a load is not
connected to the output. A monitor module turns on the power supply for a
monitor interval when the idle interval ends. During the monitor
interval, the connection module determines whether the load has been
connected to the output terminal of the power supply. An activation
module turns on the power supply if the connection module determines,
during the monitor interval, that the load has been connected to the
power supply. If the load has not been connected, another idle interval
is initiated.
