However, these terms may vary depending on the intentions of those skilled in the art, precedents, the emergence of new technologies, etc. Furthermore, in certain cases, terms may be arbitrarily selected by the applicant, and in such cases, their meanings will be described in detail in the description of the relevant embodiments of the disclosure. Therefore, the terms used in this disclosure should not be defined simply as names of terms, but rather based on the meanings of the terms and the overall content of the disclosure.

[0025] Singular expressions may include plural expressions unless the context clearly indicates otherwise. Terms used herein, including technical or scientific terms, have the same meaning as commonly understood by a person of ordinary skill in the art described herein.

[0026] Throughout this disclosure, when a part is said to "include" a component, this does not exclude other components, but rather implies the inclusion of other components, unless otherwise specifically stated.

FIG. 6 is a diagram for explaining the configuration and operation of a second power supply unit (160) according to one embodiment of the present disclosure. Hereinafter, the same configurations as those described in FIG. 2 are given the same reference numerals, and redundant descriptions are omitted.

[0118] Referring to FIGS. 2 and 5, in one embodiment of the present disclosure, FIG. 5 illustrates a conventional electronic device (400) including a conventional power supply (410) and a conventional processor (420) for explanation purposes. The conventional power supply (410) may be configured to provide a first power (500) to the conventional electronic device (400) and a second power (510) to an external electronic device (200) electrically connected to the conventional electronic device (400).

[0119] A conventional power supply unit (410) can provide first power (500) to a conventional electronic device (400) based on power supplied from an external power source, and can provide second power (510) to an external electronic device (200). The conventional power supply unit (410) can include an SMPS. The conventional power supply unit (410) can rectify AC power supplied from an external power source into DC power to provide first power (500) to the conventional electronic device (400), and can provide second power (510) to an external electronic device (200).

[0120] At this time, even if the external electronic device (200) is not electrically connected to the conventional electronic device (400) or the power of the external electronic device (200) is turned off and the external electronic device (200) is not used for the operation of the conventional electronic device (400), the conventional power supply unit (410) can rectify the AC component power supplied from the external power source in order to supply the DC component power to the conventional electronic device (400). Accordingly, there were cases where the total power consumption or total standby power of the conventional electronic device (400) was unnecessarily increased.

[0121] In contrast, referring to FIGS. 5 and 6, the electronic device (100) of the present disclosure may include a first power supply (150) for providing first power to the electronic device (100), a second power supply (160) for providing second power to an external electronic device (200), and at least one processor (140).

[0122] In one embodiment of the present disclosure, the first power supply unit (150) may include a first rectifier unit (700, see FIG. 7A). In one embodiment of the present disclosure, the first rectifier unit (700) may rectify AC power supplied from an external power source into DC power and transmit the rectified AC power to the electronic device (100) as first power (500). The first power may refer to power rectified into a DC power component.

[0123] In one embodiment of the present disclosure, the second power supply unit (160) may include a second rectifier unit (600). In one embodiment of the present disclosure, the second rectifier unit (600) may rectify AC power (630) provided from an external power source transmitted through the first power supply unit (150) into DC power (510) and transmit the rectified AC power (510) to an external electronic device (200) as second power (510). The second power (510) may refer to power (510) rectified into a DC power component.

[0124] In one embodiment of the present disclosure, the second power supply unit (160) may include a switching unit (610). The second rectifier unit (600) may be electrically connected to the first power supply unit (150) through the switching unit (610). In one embodiment of the present disclosure, at least one processor (140) may generate a control signal (620) for controlling the turning on or off of the switching unit (610) through the switching control module (133). At least one processor (140) may turn on or off the switching unit (610) based on the control signal (620). The switching unit (610) may be implemented as an analog switch integrated circuit (IC), a transistor-based switch (e.g., a metal oxide semiconductor field effect transistor (MOSFET) or a bipolar junction transistor (BJT)), or a relay switch (e.g., an electromechanical relay or a solid state relay (SSR)), and various other options may be possible.

[0125] In one embodiment of the present disclosure, when the external electronic device (200) is not electrically connected to the electronic device (100) or the power of the external electronic device (200) is turned off, at least one processor (140) can turn off the switching unit (610). Accordingly, the AC component power supplied from the external power source to the second rectifier unit (600) through the first power supply unit (150) can be stopped.

[0126] In this case, the first power supply unit (150) may only require AC power to transmit the first DC power (500) from the external power source to the electronic device (100). Accordingly, the total power consumption or total standby power of the electronic device (100) can be prevented from increasing unnecessarily.

FIG. 7B is a diagram for explaining an operation when power is stopped from being provided to an external electronic device (200) through a second power supply unit (160) according to an embodiment of the present disclosure. Hereinafter, the same components as those described in FIGS. 3 and 6 are given the same reference numerals, and redundant descriptions are omitted.

[0128] Referring to FIGS. 3, 4A, and 7A, in one embodiment of the present disclosure, power (710) may be supplied to the first power supply (150) from an external power source. The power (710) provided to the first power supply (150) from the external power source may be the sum of power (720) for the first power (500) provided to at least one processor (140) through the first power supply (150) and power (630) for the second power (510) provided to the second power supply (160) through the first power supply (150) and provided to the external electronic device (200).

[0129] Hereinafter, for convenience of explanation, power (710) provided from an external power source to the first power supply unit (150) may be referred to as first input power (710). Power (720) for providing first power (500) to at least one processor (140) through the first power supply unit (150) may be referred to as second input power (720). Power (630) provided to the second power supply unit (160) to provide second power (510) to an external electronic device (200) through the first power supply unit (150) may be referred to as third input power (630).

[0130] In one embodiment of the present disclosure, the first power supply (150) can provide first power (500) to at least one processor (140) based on second input power (720). Although FIG. 7A illustrates the first power supply (150) providing the first power (500) to at least one processor (140), the present disclosure is not limited thereto. The first power (500) can be power for driving the electronic device (100). The first power supply (150) can provide the first power (500) to the electronic device (100).

[0131] In one embodiment of the present disclosure, the first power supply (150) may include a first rectifier (700). Each of the first input power (710), the second input power (720), and the third input power (630) may be AC ​​power. The first rectifier (700) may rectify the second input power (720) into a DC component and transmit the DC component to at least one processor (140) as the first power (500).

[0132] In one embodiment of the present disclosure, the second power supply unit (160) may include a second rectifier unit (600) and a switching unit (610). In one embodiment of the present disclosure, the first power supply unit (150) and the second power supply unit (160) may have different configurations. In one embodiment of the present disclosure, the first power supply unit (150) and the second power supply unit (160) may be physically separated.

[0133] In one embodiment of the present disclosure, at least one processor (140) can determine whether an external electronic device (200) and the electronic device (100) are electrically connected. Although FIG. 7A illustrates that the external electronic device (200) and at least one processor (140) are connected via an input / output interface (730), the present disclosure is not limited thereto. In one embodiment of the present disclosure, the external electronic device (200) may also be electrically connected to at least one processor (140) via other components of the electronic device (100).

[0134] In one embodiment of the present disclosure, at least one processor (140) can determine whether the power of an external electronic device (200) is turned on or off. Hereinafter, the operation of at least one processor (140) determining whether the external electronic device (200) and the electronic device (100) are electrically connected and the power status of the external electronic device (200) will be described later with reference to FIG. 8.

[0135] In one embodiment of the present disclosure, at least one processor (140) may generate a control signal (620) to turn on the switching unit (610) when it is determined that the external electronic device (200) is electrically connected to the electronic device (100) and the power of the external electronic device (200) is turned on. At least one processor (140) may turn on the switching unit (610) based on the generated control signal (620).

[0136] In one embodiment of the present disclosure, as the switching unit (610) is turned on, the first power supply unit (150) and the second power supply unit (160) are electrically connected, and the external power can supply the first input power (710) of the size of the second input power (720) and the third input power (630) to the first power supply unit (150). In one embodiment of the present disclosure, the second power supply unit (160) can obtain the third input power (630) from the external power source through the first power supply unit (150).

[0137] In one embodiment of the present disclosure, the second rectifier (600) can rectify the third input power (630) provided through the switching unit (610) into a direct current component and transmit the rectified third power (630) to an external electronic device (200) as second power (510). Although FIG. 7A illustrates that the second power (510) is transmitted to the external electronic device (200) through at least one processor (140), the present disclosure is not limited thereto. In one embodiment of the present disclosure, the second power (510) may also be transmitted to the external electronic device (200) through another configuration of the electronic device (100) or an input / output interface for power transmission.

[0138] Additionally, although FIG. 7A illustrates that the second power supply unit (160) includes a second rectifier (600), the present disclosure is not limited thereto. The second power supply unit (160) may include only a switching unit (610) and may not include a second rectifier.

[0139] In this case, the second power supply unit (160) may transmit the third input power (630) of the AC component provided from the external power source through the first power supply unit (150) to the external electronic device (200). At this time, the third input power (630) of the AC component may be provided to the external electronic device (200) as the second power (510). At least one processor (140) may provide the second power (510) of the AC component to the external electronic device (200) through the second power supply unit (160).

[0140] Referring to FIGS. 7A and 7B, in one embodiment of the present disclosure, FIG. 7B illustrates that at least one processor (140) generates a control signal (621) to turn off the switching unit (610) when it is determined that the external electronic device (200) is not electrically connected to the electronic device (100). In addition, at least one processor (140) may also generate a control signal (621) to turn off the switching unit (610) when it is determined that the power of the external electronic device (200) is turned off even if the external electronic device (200) is electrically connected to the electronic device (100).

[0141] In one embodiment of the present disclosure, when the switching unit (610) is turned off, the first power supply unit (150) and the second power supply unit (160) may not be electrically connected. The first input power (710) supplied by the external power source to the first power supply unit (150) may have the same size as the second input power (720). In one embodiment of the present disclosure, the first rectifier unit (700) may rectify the second input power (720) into a direct current component and provide the direct current component as the first power (500) to at least one processor (140).

[0142] In one embodiment of the present disclosure, the second rectifier (600) included in the second power supply (160) may not be electrically connected to the first power supply (150) by the turned-off switching unit (610). Accordingly, the supply of AC power from the external power source to the second power supply (160) through the first power supply (150) may be interrupted.

[0143] In one embodiment of the present disclosure, when it is determined that an external electronic device (200) is not electrically connected to the electronic device (100) or that the power of the external electronic device (200) is turned off, the electronic device (100) may turn off the switching unit (610) so that the second power supply unit (160) for supplying power to the external electronic device (200) and the first power supply unit (150) for supplying power to the electronic device (100) are not electrically connected.

[0144] Accordingly, it is possible to prevent the total power consumption or total standby power of the electronic device (100) from being unnecessarily increased in order to provide power to an external electronic device (200). Specifically, it is possible to prevent AC power from being unnecessarily provided to the second rectifier (600) included in the second power supply unit (160), thereby preventing power loss from occurring in the process of rectifying AC power into DC power.

[0145] In one embodiment of the present disclosure, when the external electronic device (200) is not electrically connected to the electronic device (100) or the power of the external electronic device (200) is turned off, the external power source can provide only the second external power (720) required by the first power supply unit (150) to the electronic device (100). Accordingly, the total power consumption or total standby power of the electronic device (100) can be efficiently managed.

[0146] FIG. 8 is a diagram for explaining an operation of determining whether an external electronic device (200) is connected and whether the power of the external electronic device (200) is turned on or off according to one embodiment of the present disclosure.

In this case, the first terminal may include a general purpose input / output (GPIO) pin.

[0150] In one embodiment of the present disclosure, the voltage level of the first terminal configured to be electrically connected to the other end of the first input / output interface (731) may be set to a High value in a state where the first terminal is not electrically connected to the outside. In this case, the High value may mean a value greater than an arbitrary reference value and may mean "1" as a digital value. In one embodiment of the present disclosure, the arbitrary reference value may be a value greater than 0.

[0151] In one embodiment of the present disclosure, when the first terminal is electrically connected to the ground terminal of an external electronic device (200) via the first input / output interface (731), the voltage level of the first terminal may have a Low value. In this case, the Low value may mean a value that is electrically connected to the ground terminal and is lower than an arbitrary reference value, and may mean "0" as a digital value.

[0152] In one embodiment of the present disclosure, at least one processor (140) can determine whether an external electronic device (200) is electrically connected to the electronic device (100) based on a voltage level of a multi-purpose input / output pin. If the voltage level of the first terminal has a High value, the at least one processor (140) can determine that the external electronic device (200) is not electrically connected to the electronic device (100). If the voltage level of the first terminal has a Low value, the at least one processor (140) can determine that the external electronic device (200) is electrically connected to the electronic device (100).

[0153] In one embodiment of the present disclosure, one end of the second input / output interface (732) may be electrically connected to a terminal that provides a status of whether the power of the external electronic device (200) is turned on or off. In one embodiment of the present disclosure, the other end of the second input / output interface (732) may be electrically connected to at least one processor (140) included in the electronic device (100). Specifically, the other end of the second input / output interface (732) may be electrically connected to a second terminal of at least one processor (140). In this case, the terminal that provides a status of whether the power of the external electronic device (200) is turned on or off may be a terminal defined by the OPS standard.

In one embodiment of the present disclosure, the standby mode may refer to a mode in which the electronic device (100) operates by receiving standby power from an external power source.

[0159] In one embodiment of the present disclosure, in the step (S50) of determining whether the electronic device (100) is operating in a normal mode or a standby mode, at least one processor (140) can determine whether the electronic device (100) is operating in a normal mode or a standby mode based on a currently running program or content, etc.

[0160] In one embodiment of the present disclosure, when it is determined that the electronic device (100) is operating in a normal mode, the operating method of the electronic device (100) may include a step (S100) of providing first power to the electronic device (100) through a first power supply (150). In one embodiment of the present disclosure, in the step (S100) of providing first power to the electronic device (100), at least one processor (140) may provide the first power to the electronic device (100) through the first power supply (150).

[0161] In addition, since it is determined that the electronic device (100) is operating in a normal mode, the operating method of the electronic device (100) may include a step (S200) of determining whether the external electronic device (200) and the electronic device (100) are electrically connected.

[0166] In one embodiment of the present disclosure, since the electronic device (100) does not provide content (300) through the display (110) in the standby mode, the electronic device (100) does not need to receive data such as still images, moving images, or audio signals from the external electronic device (200). In addition, the electronic device (100) does not need to be operated using the operating system included in the external electronic device (200) to display the content (300). Therefore, since there is no need to drive the external electronic device (200), the provision of secondary power to the external electronic device (200) can be stopped. In one embodiment of the present disclosure, when at least one processor (140) determines that the electronic device (100) is operated in the standby mode, it may turn off the switching unit (610, see FIG. 7B) to not provide secondary power to the external electronic device (200) through the second power supply unit (160).

[0176] FIG. 10 is a diagram illustrating a power supply unit that supplies power to an electronic device and an external electronic device according to one embodiment of the present disclosure. Hereinafter, the same components as those described in FIG. 7a are assigned the same reference numerals, and any redundant descriptions are omitted.

[0177] Referring to FIGS. 3, 7A, and 10, in one embodiment of the present disclosure, the electronic device (100) illustrated in FIG. 10 may include a power supply unit (1000) and at least one processor (140). For convenience of explanation, FIG. 10 illustrates the electronic device (100) as including the power supply unit (1000) and at least one processor (140), but it is to be understood that the electronic device (100) may include other components such as a display (110), a memory (130), and the like.

[0178] In one embodiment of the present disclosure, the power supply unit (1000) illustrated in FIG. 10 may include a first rectifier unit (1010), a second rectifier unit (1020), and a switching unit (1230). In one embodiment of the present disclosure, the power supply unit (1000) may provide first power (500) to at least one processor (140) and second power (510) to an external electronic device (200) based on power (710) supplied from an external power source.

[0179] In one embodiment of the present disclosure, at least one processor (140) may be connected to an external electronic device (200) via an input / output interface (730). In one embodiment of the present disclosure, at least one processor (140) may check whether the external electronic device (200) and the electronic device (100) are electrically connected and the power status of the external electronic device (200), and may generate a control signal (620) for controlling the status of the switching unit (1230).

[0180] In one embodiment of the present disclosure, FIG. 10 illustrates that an external electronic device (200) is electrically connected to an electronic device (100), and when the power of the external electronic device (200) is determined to be turned on, at least one processor (140) turns on a switching unit (1230) through a control signal (620).

[0181] In one embodiment of the present disclosure, as the switching unit (1230) is turned on, the first input power (710) of the AC component supplied to the power supply unit (1000) from the external power source may be the sum of the second input power (720) of the AC component for providing the first power (500) and the third input power (630) of the AC component for providing the second power (510).

[0182] In one embodiment of the present disclosure, the first rectifier (1010) can rectify the second input power (720) into a DC component and provide the DC component as the first power (500) to at least one processor (140). The second rectifier (1020) can rectify the third input power (630) into a DC component and provide the DC component as the second power (510) to an external electronic device (200).

[0183] In one embodiment of the present disclosure, when it is determined that an external electronic device (200) is electrically connected to the electronic device (100) or that the power of the external electronic device (200) is turned off, at least one processor (140) can turn off the switching unit (1230) through a control signal (620).

[0184] In one embodiment of the present disclosure, in this case, the magnitude of the first input power (710) of the AC component supplied to the power supply unit (1000) from the external power source may be equal to the second input power (720). Since the first rectifier unit (1010) and the external power source and the second rectifier unit (1020) are not electrically connected by the turned-off switching unit (1230), the supply of the second input power (720) of the AC component from the external power source to the second rectifier unit (1020) may be stopped.

[0185] Through this, when the external electronic device (200) is not electrically connected to the electronic device (100) or the power of the external electronic device (200) is turned off and there is no need to supply power to the external electronic device (200), the AC component power is prevented from being unnecessarily supplied to the second rectifier (600), thereby efficiently managing the total power consumption or total standby power of the electronic device (100).
