Abstract
In an embodiment, a switching converter includes: a switching stage including first and second switching devices for receiving an input voltage and for providing an output voltage; a driving stage including first and second driving devices for driving the first and second switching devices, respectively; a current sensing arrangement for sensing an output current provided by the switching stage; a voltage generation arrangement configured to generate a supply voltage for powering the driving stage, the voltage generation arrangement being configured to adjust the supply voltage according to the sensed output current; and a charge recovery stage configured to store a first electric charge being lost from the first driving device during driving of the first switching device and to release at least partially the stored first electric charge to the second driving device during driving of the second switching device.
