Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to the field of power supply, and more particularly to an electronic device and a power supply device thereof. [Prior Art] [0002] Electronic devices are almost ubiquitous in people's lives. There are two main types of power supply for electronic equipment, one is battery-powered, and the other is an external power supply or power adapter. Please refer to FIG. 1, which is a system architecture diagram of a general electronic device 10, which includes a power supply device 100 and a main system 150. The power supply unit 100 is for receiving an input of an external power source, and converting the external power source into a working voltage required by the main system 150 and supplying it to the main system 150. The main system 150 is used for the functional realization of the electronic device 10. If the electronic device 10 is a DVD, the main system 150 is used to play the optical disc. The power supply device 100 includes a power input interface 102, a first power converter 104, a power manager 106, and a second power converter 108. The power input interface 102 is a power input interface for receiving an external power source. The first power converter 104 is used to convert the external power source to the operating voltage required by the power manager 106 and to the power manager 106. The power manager 106 receives the operating voltage for system power management and sends a start command to the second power converter 108. The second power converter 108 starts operating based on the start command and converts the external power source to the operating voltage required by the host system 150 and provides it to the host system 150. Typically, the electronic device 10 further communicates with the power manager 106 during operation to enable better power management. 096151229 Form No. A0101 Page 4/Total 15 Page 1003374599-0 1363473 October 10th, 2010. Shuttle Page _ [0005] As can be seen from the operation of the power supply device 100 of the electronic device 10 described above, the main system 15 0 works. At the same time, the first power converter 104 and the second power converter 108 are also always operating, so that the power consumption of the electronic device 10 is large.

The power supply unit 200 is for receiving an input of a power source, and converting the external power source into an operating voltage required by the main system 250 and supplying it to the main system 250. [0012] The power supply device 200 includes a power input interface 202, a control unit 204, a first power converter 206, a power manager 208, a protection unit 210, and a second power converter 212.

[0014] The first power converter 206 is used to receive power and convert it into power management 1003374599-0 096151229 Form No. A0101 Page 6 / Total 15 Page 1363743 100 years. October 12th is required to replace the pager 208 The operating voltage ' is supplied to the power manager 208. Since the first power converter 206 can start working after receiving the power supply to ensure that the subsequent module can work normally, the first power converter 2〇6 is a DC/DC (DC-DC transformer) circuit composed of discrete components. [0015] The power manager 208 is configured to respectively send a start command and a stop command to the second power converter 212 and the control unit 2〇4 after receiving the operating voltage. [0016] The second power converter 212 is configured to start operation based on the startup command to convert the external power source into an operating voltage required by the power manager 2〇8 and an operating voltage required by the main system 25 0 and provide respectively The power manager 2〇8 and the main system 250 are provided. Since the operation of the main system 250 requires a relatively stable voltage and in order to reduce power consumption, the second power converter 212 is typically a semiconductor DC/DC (DC-DC transformer) which requires a start signal to start operation. [0017] The control unit 204 is connected between the power input interface 2〇2 and the first power converter 206 for turning off the operation of the first power converter 206 according to the stop command, and the closing action may be disconnecting The power input of a power converter 206 is either reduced or reduced to a minimum operating voltage of the first power converter 206. [0018] The protection unit 210 is connected to the second power converter 212 to transmit the operating voltage to the channel of the power manager 208. 'For preventing the voltage output by the first power converter 206 from flowing to the second power converter 212, the circuit is avoided. [0019] Please refer to FIG. 2, which is a more detailed circuit diagram of the electronic device 20. The control unit 204 is an electronic switch including resistors R1, R2, R3 and an NPN type triode Q1. The collector of diode Q1 is connected to the power supply by resistor R1. 096151229 Form No. A0101 Page 7 / Total 15 Page 1003374599-0 1363473 October 12, 100 Shuttle Replacement Page · Input Interface 202 and First Power Converter Between 206; the base of the triode Q1 is connected to the power manager 208 by a resistor R2; the emitter of the triode Q1 is grounded; one end of the resistor R3 is connected between the resistor R2 and the power manager 208, and the other end is grounded. . [0020] The protection unit 210 in the electronic device 20 is a Schottky diode D1, the anode of which is connected to the second power converter 212, and the cathode is connected to the power manager 208.
[0021] 電源輸入介面202接收到外部電源後，第一電源轉換器 206將外部電源轉化成電源管理器208的工作電壓，並傳 送給電源管理器208。電源管理器208接收工作電壓後啟 動第二電源轉換器212。第二電源轉換器21 2啟動後輸出 兩路工作電壓，一路提供給主系統250，一路藉由二極體 D1提供給電源管理器208。然後，電源管理器208給三極 體Q1—個高電平使三極體Q1導通，第一電源轉換器206的 電源輸入端藉由電阻R1和三極體Q1接地，導致第一電源 轉換器206的輸入電源低於其最低工作電壓而停止工作。 此時的電源管理器208的工作電壓由第二電源轉換器212 提供。所述二極體D1用於防止第一電源轉換器206輸出給 電源管理器208的工作電壓流向第二電源轉換器212，保 障第二電源轉換器212的電氣安全。 [0022] 綜上所述，上述電子設備20的第一電源轉換器206只是在 啟動時工作，待第二電源轉換器212正常工作後第一電源 轉換器206被關閉，從而減少了電子設備20的耗電模組， 降低了系統功耗，節約了電能。 096151229 表單编號A0101 第8頁/共15頁 1003374599-0 1363473 100年10月12日俊正替換頁 [0023] 本技術領域的普通技術人員應當認識到，以上的實施方 式僅是用來說明本發明，而並非用作為對本發明的限定 ，只要在本發明的實質精神範圍之内，對以上實施例所 作的適當改變和變化都落在本發明要求保護的範圍之内 【圖式簡單說明】 [0024] 圖1為通常的電子設備之系統架構圖。 [0025] 圖2為一較佳實施方式之電子設備的系統架構圖。[0021] After the power input interface 202 receives the external power source, the first power converter 206 converts the external power source into the operating voltage of the power manager 208 and transmits it to the power manager 208. The power manager 208 activates the second power converter 212 after receiving the operating voltage. The second power converter 21 2 starts to output two operating voltages, one for the main system 250, and one for the power manager 208 by the diode D1. Then, the power manager 208 turns the transistor Q1 into a high level to turn on the transistor Q1. The power input terminal of the first power converter 206 is grounded through the resistor R1 and the transistor Q1, resulting in the first power converter. The input power to 206 stops operating below its minimum operating voltage. The operating voltage of the power manager 208 at this time is provided by the second power converter 212. The diode D1 is used to prevent the operating voltage output from the first power converter 206 to the power manager 208 from flowing to the second power converter 212 to ensure electrical safety of the second power converter 212. [0022] In summary, the first power converter 206 of the electronic device 20 is only operated at startup, and the first power converter 206 is turned off after the second power converter 212 is working normally, thereby reducing the electronic device 20. The power consumption module reduces system power consumption and saves power. 096151229 Form No. A0101 Page 8 of 15 1003374599-0 1363473 October 12, 100 Correct Replacement Page [0023] One of ordinary skill in the art will recognize that the above embodiments are merely illustrative of the present invention.
