Abstract
Official abstract text for this publication.
A power supply system and method are disclosed. The system includes a switching stage to provide an output current through an output inductor in response to a switching signal having a substantially fixed duty-cycle. The system also includes a load monitor to monitor a load of the power supply system. The system further includes a gate drive controller to generate the switching signal and to change operation of the switching stage from a normal operating mode to a light-load operating mode in response to the load being less than a predetermined threshold to substantially minimize a voltage across the output inductor in the light-load operating mode.
First claim
Opening claim text (preview).
What is claimed is: 1. A power supply system comprising: a switching stage to provide an output current through an output inductor in response to a switching signal having a substantially fixed duty-cycle; a load monitor to monitor a load of the power supply system; and a gate drive controller to generate the switching signal and to change operation of the switching stage from a normal operating mode to a light-load operating mode in response to the load being less than a pred…
