Abstract
A converter and a method of operating a switching converter in a low power mode are presented. The invention relates to a III/V semiconductor switching converter. A switching converter contains a first power switch coupled to a second power switch via a switching node. There is an inductor coupled to the switching node, and a clamp circuit containing a third power switch is coupled in parallel to the first power switch. The switching converter is adapted to turn the first power switch off and to enable control of the third power switch upon identifying that the switching converter provides a low level of power.
