[0055] According to one embodiment, with reference to FIG. 4A, a first phase operation of a first converting operation (e.g., a 3:1 converting operation) of a switched capacitor converter (210) is described as follows. A first capacitor (321) may be connected to an output terminal of the switched capacitor converter (210) while being charged by power provided through an input terminal of the switched capacitor converter (210) based on the first switch (301) and the fourth switch (304) being turned on.

The third capacitor (323) can be connected to the output terminal of the switched capacitor converter (210) through the fourth capacitor (324) while being discharged based on the ninth switch (309) and the eleventh switch (311) being turned on. The fourth capacitor (324) can be connected to the output terminal of the switched capacitor converter (210) while being charged based on the power provided from the third capacitor (323) based on the ninth switch (309) and the eleventh switch (311) being turned on.

Referring to FIGS. 5A and 5B, the 2:1 converting may be a case where the ratio of the input voltage (e.g., Vin) of the input terminal of the switched capacitor converter (210) to the output voltage (e.g., Vout) of the output terminal of the switched capacitor converter (210) is 2:1. For the second converting operation (e.g., 2:1 converting operation) of the switched capacitor converter (210), the third phase operation and the fourth phase operation can be performed alternately. The electronic device (101) (e.g., controller (220)) can alternately perform the third phase operation and the fourth phase operation for the second converting operation (e.g., 2:1 converting operation) of the switched capacitor converter (210).

[0060] According to one embodiment, referring to FIG. 5A, the third phase operation may include an operation of controlling the third switch (303), the seventh switch (307), and the eighth switch (308) to turn on. The third phase operation may include an operation of controlling the first switch (301), the fourth switch (304), the tenth switch (310), and the twelfth switch (312) to turn on. The third phase operation may include an operation of controlling the second switch (302), the fifth switch (305), the sixth switch (306), the ninth switch (309), and the eleventh switch (311) to turn off. For example, the electronic device (101) (e.g., the controller (220)) can control the switched capacitor converter (210) so that the third phase operation simultaneously performs an operation of controlling the third switch (303), the seventh switch (307), and the eighth switch (308) to turn on, an operation of controlling the first switch (301), the fourth switch (304), the tenth switch (310), and the twelfth switch (312) to turn on, and an operation of controlling the second switch (302), the fifth switch (305), the sixth switch (306), the ninth switch (309), and the eleventh switch (311) to turn off.

[0061] According to one embodiment, referring to FIG. 5B, the fourth phase operation may include an operation of controlling the third switch (303), the seventh switch (307), and the eighth switch (308) to be turned on.

The fourth phase operation may include an operation of controlling the second switch (302), the fifth switch (305), the ninth switch (309), and the eleventh switch (311) to be turned on. For example, the electronic device (101) (e.g., the controller (220)) can control the switched capacitor converter (210) so that the following operations are simultaneously performed: controlling the third switch (303), the seventh switch (307), and the eighth switch (308) to turn on; controlling the first switch (301), the fourth switch (304), the sixth switch (306), the tenth switch (310), and the twelfth switch (312) to turn off; and controlling the second switch (302), the fifth switch (305), the sixth switch (306), the ninth switch (309), and the eleventh switch (311) to turn on.

[0062] According to one embodiment, with reference to FIG. 5A, the third phase operation of the second converting operation (e.g., 2:1 converting operation) of the switched capacitor converter (210) is described as follows. The first capacitor (321) may be connected to the output terminal of the switched capacitor converter (210) while being charged by power provided through the input terminal of the switched capacitor converter (210) based on the first switch (301) and the fourth switch (304) being turned on. The fourth capacitor (324) may be connected to the output terminal of the switched capacitor converter (210) while being discharged based on the tenth switch (310) and the twelfth switch (312) being turned on. For reference, in FIGS. 5A and 5B, the second capacitor (322) may not function as a flying capacitor because it is continuously connected to the output terminal of the switched capacitor converter (210) based on the fact that the third switch (303) and the seventh switch (307) are continuously turned on. Similarly, in FIGS. 5A and 5B, the third capacitor (323) may not function as a flying capacitor because it is continuously connected to the input terminal of the switched capacitor converter (210) based on the fact that the eighth switch (308) and the seventh switch (307) are continuously turned on.

[0063] According to one embodiment, with reference to FIG. 5B, the fourth phase operation of the second converting operation (e.g., 2:1 converting operation) of the switched capacitor converter (210) is described as follows.

[0064] As a result, based on the third phase operation of FIG. 5A and the fourth phase operation of FIG. 5B, the ratio of the input voltage Vin of the input terminal of the switched capacitor converter (210) to the output voltage Vout of the output terminal of the switched capacitor converter (210) becomes 2:1. According to one embodiment, the third capacitor (323) may have a withstand voltage that is at least twice the output voltage Vout for the 2:1 converting operation (e.g., the third phase operation of FIG. 5A and the fourth phase operation of FIG. 5B). According to one embodiment, the first capacitor (321), the second capacitor (322), and the fourth capacitor (324) may have withstand voltages that are at least twice the output voltage Vout for the 2:1 converting operation (e.g., the third phase operation of FIG. 5A and the fourth phase operation of FIG. 5B).
