Current-parking switching regulator downstream controller

Abstract

A system and method are provided for regulating a voltage level at a load. A current source generates a current and a voltage control mechanism provides a portion of the current to regulate the voltage level at the load. When the voltage level at the load is greater than a maximum voltage level, the current source is decoupled from the load and the current source is coupled to a current sink to reduce the voltage level at the load. An electric power conversion comprises the current source and the voltage control mechanism. A downstream controller is configured to control the voltage control mechanism to decouple the current source from the load and couple the current source to a current sink to reduce the voltage level at the load when the voltage level at the load is greater than a maximum voltage level.
