1. A switching converter for converting a direct current input voltage into a direct current output voltage, the switching converter comprising:
a switching stage configured to receive the input voltage, receive a driving signal for driving the switching stage, and provide the output voltage according to the input voltage and the driving signal;
a driving stage configured to provide the driving signal to the switching stage;
a current sensing circuit configured to sense an output current provided by the switching stage; and
a voltage generation circuit configured to generate at least one supply voltage for powering the driving stage, and adjust the at least one supply voltage according to the output current,
wherein the switching stage comprises first and second switching devices, wherein the driving stage comprises first and second driving devices configured to drive the first and second switching devices, respectively, and wherein the voltage generation circuit comprises a first voltage generation stage configured to generate, according to the output current, a first supply voltage for powering the second driving device, and a second voltage generation stage configured to generate a second supply voltage for powering the first driving device, and
wherein the second voltage generation stage is configured to generate the second supply voltage according to a reference voltage corresponding to the first supply voltage.
