description A buck-boost converter (100) includes an inductor (L), a first switch (SW1), a second switch (SW2), a third switch (SW3), a fourth switch (SW4) and a fifth switch (SW5), wherein the first switch (SW1) is coupled between an input voltage and a first terminal (N1) of the inductor (L), the second switch (SW2) is coupled between a reference voltage and the first terminal (N1) of the inductor (L), the third switch (SW3) is coupled between an output voltage and a second terminal (N2) of the inductor (L), the fourth switch (SW4) is coupled between the reference voltage and the second terminal (N2) of the inductor (L), and the fifth switch (SW5) is connected in parallel with the third switch (SW3). When the buck-boost converter (100) operates in a buck mode, the first switch (SW1) and the second switch (SW2) are turned on alternately; when the buck-boost converter (100) operates in a boost mode, the third switch (SW3) and the fourth switch (SW4) are turned on alternately; and the fifth switch (SW5) is controlled by a mode control signal.
