Abstract
In accordance with various aspects of the present invention, a method and circuit for reducing power consumption of a power module during idle conditions is provided. In an exemplary embodiment, a power module is configured for reducing power during idle mode by disengaging at least one power output from a power input. A power module may include one or more power outputs and one or more power module circuits, with power input connected to the power outputs through the power module circuit(s). The power module circuit may include a current measuring system, a control circuit, and a switch. The current measuring system provides an output power level signal that is proportional to the load at the power output. If current measuring system behavior indicates that a power output is drawing substantially no power from the power input, the switch disengages the power input from the power output.
