Problems solved by technology

[0010] However, the design of the timing control circuit of the existing front-side bus power supply is generally only suitable for the situation that the CPU load current is small. When operating, the traditional front-side bus power sequence control circuit design may not be applicable, which may cause the computer to fail to boot or automatically restart.

Abstract

The invention provides a time sequence control circuit, which is used for providing a time sequence control signal for a front-end bus power supply of a computer. The time sequence control circuit comprises an electronic switch and two voltage-sharing resistors, wherein the two voltage-sharing resistors are connected in series with each other and are connected to a system power supply and grounded respectively; the time sequence control signal is output between the two voltage-sharing resistors; the first end of the electronic switch is electrically connected with the two voltage-sharing resistors, and the second end of the electronic switch is electrically connected to a control signal end of the computer; and the level of the control signal end and the level of the time sequence control signal are set at the same phase. The invention also relates to a front-end bus power supply with the time sequence control circuit.

Description

technical field [0001] The invention relates to a sequence control circuit, in particular to a computer front-side bus power supply sequence control circuit and a front-side bus power supply with the sequence control circuit. Background technique [0002] A front side bus (Front Side Bus, FSB) is a bus used to connect a computer central processing unit (Central Processing Unit, CPU) to a north bridge chip. Generally speaking, the front-side bus is the most important channel for exchanging data between the CPU and the outside world, so the data transmission capability of the front-side bus has a great effect on computing and overall performance. The stability of the front-side bus power supply has a great impact on its data transmission capability. [0003] The existing FSB power supply generally includes the following functional modules: [0004] An advanced configuration and power management interface (Advanced Configuration and Power Management Interface, ACPI) chip; ...
