A switching converter circuit comprises at least an input terminal (IN1) for connecting to a continuous voltage source (VDCbus), an integrated control circuit (20), a pair of field effect transistors (QH, QL) connected to the integrated control circuit (20), a pair of coupled inductors (10) connected to the pair of field effect transistors (QH, QL), a diode (D) connected to the pair of field effect transistors (QH, QL), a pair of capacitors (Cn, Cled), and a first output terminal (OUT1). The converter circuit (1) further comprises a control loop (100) for controlling a current in output from the circuit via the first output terminal (OUT1).
