1. A switching converter comprising:
an input line;
an output line;
a ground line;
a switching node;
an inductor having a first end directly coupled to the switching node and a second end coupled to the output line;
an output capacitor connected to the output line;
a first switch and a second switch connected in series between the input line and the ground line;
a third switch having a first end directly coupled to the switching node and a second node coupled to the input line;
a flying capacitor connected across the third switch and the first switch, wherein one end of the flying capacitor is directly coupled to the switching node; and
a controller circuit structured to drive the first switch to the third switch, wherein the controller circuit alternately repeats:
a first state in which the second switch and the third switch are turned on and the first switch is turned off; and
a second state in which the second switch and the third switch are turned off and the first switch is turned on.
