Embodiment Construction

[0041] In the description and the following claims, the term coupled herein includes any direct and indirect electrical connection means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means. In addition, the positive phase signal is a state of a digital logic signal, or can be understood as a general digital logic signal state 1, and the negative phase signal is a state of another digital logic signal, or can be understood as a general digital logic signal state 0.

[0042] figure 1 It is a schematic diagram of a motherboard 100 according to an embodiment of the present invention. The motherboard 100 is suitable for computer devices, including applications such as integrated desktop computers, embedded systems, barebone systems, and digital home theater compu...

Abstract

The invention provides a motherboard and its power control method, which is suitable for a computer device. The mainboard includes: a first power supply slot for connecting a first power supply and providing a first voltage; a voltage conversion circuit having a voltage conversion input terminal to receive the first voltage through the first power supply slot, And the voltage conversion output terminal provides the first standby voltage, which is converted from the first voltage; the second power supply slot is used for connecting the second power supply and provides the second standby voltage; the power control unit has the first power supply The control input terminal receives the first standby voltage, the second power control input terminal receives the second standby voltage through the second power socket, and the power control output terminal provides a standby voltage source for use by the computer device in the standby state.

Description

technical field [0001] The present invention relates to a motherboard and its power control method, in particular to a motherboard applicable to different types of power supplies and its power control method. Background technique [0002] At present, the most common motherboard specification in assembled computers is the ATX standard, which was formulated and announced by the American Intel Corporation in 1995. The content includes the size of the motherboard and the specification design related to the power supply. The number and length of the cables, and also supply the power of the core components on the motherboard, and also meet the power requirements of the external graphics card. A power supply that complies with the ATX standard, and its connection terminals include the following voltage sources: positive 3.3 volts, positive 5 volts, standby 5 volts, positive 12 volts, negative 12 volts, ground; and signal: voltage source Start (power on), voltage source complete st...
