摘要：
An apparatus, system, and method are disclosed for a switching power supply with high efficiency near zero load conditions. A power detection module detects power provided to a load. The switching power supply is capable of operating in a zero voltage switching mode. The power detection module detects when the load power falls below a minimum power threshold. A low load power control module operates the switching power supply in a low load mode if the power detection module detects that the power to the load is below the minimum power threshold. The low load mode includes operating the power supply in zero voltage switching mode in response to an output voltage of the power supply falling below a regulation voltage threshold. The low load mode includes turning off switching of the power supply in response to the output voltage of the power supply rising above the regulation voltage threshold.
