Wherein, said voltage conversion circuit I comprises controller I; Carry out after voltage transformation accomplishes when the output signal of said AND circuit I drives said voltage conversion circuit I, said controller I sends the POWER_GOOD signal and gives said voltage conversion circuit II.
Wherein, said voltage conversion circuit II comprises controller II; After said voltage conversion circuit II receives said POWER_GOOD signal, carry out voltage transformation, after said voltage transformation was accomplished, said controller II sent the POWER_GOOD signal, and was the PS_PWROK signal with said POWER_GOOD conversion of signals.
Wherein, said voltage conversion circuit I and said voltage conversion circuit II include DC-DC transfer circuit.
Wherein, said voltage conversion circuit I becomes 12V voltage into 5V voltage.
Wherein, said voltage conversion circuit II becomes 12V voltage into 3V voltage.
Wherein, said AND circuit can be made up of at least two triode; The base stage of each said triode is as signal input part, the grounded emitter of each said triode, and the collector of at least two said triodes interconnects the back as signal output part.
Wherein, said AND circuit can be and the door chip, can adopt the 74LVC1G08 of NXP company.
With the prior art ratio, beneficial effect of the present invention is:
Among the present invention, because the processor and the chipset of the low-power consumption of using, each node consumed current is less, and the power supply between each node can be realized sharing, and has saved mainboard space and cost.
The present invention has realized that the power supply between each node is shared, and has only just realized power-on and power-off time sequence control in the shared design proposal of power supply through some and door, and circuit is simple, realization easily, and cost is lower.

Embodiment
Do further to specify below in conjunction with the accompanying drawing specific embodiments of the invention.
The main design of the shared formula power circuit of a kind of blade type microserver that present embodiment provides is as shown in Figure 2, and the feed circuit in its comparison diagram 1 only need a cover voltage conversion circuit can realize the power supply to a plurality of nodes among Fig. 2.In view of the above, the circuit diagram that present embodiment proposes is as shown in Figure 3, mainly comprises voltage conversion circuit I, voltage conversion circuit II and at least two s' AND circuit.Present embodiment is the example explanation with four nodes.
As shown in Figure 3; On four nodes the SLP_S3# signal of South Bridge chip output and CPU signal on the throne through with door after the PSON signal end of generation as the input end of an AND circuit I; The output terminal of AND circuit I is connected with said DC-DC transfer circuit II with said DC-DC transfer circuit I successively; The output signal of DC-DC transfer circuit II output terminal is divided into four the tunnel, and the SLP_S3# signal of each a road signal and a node is as the input signal of AND circuit II, and the output signal of said AND circuit II is controlled each node postorder power circuit respectively (like CPU; The powering on power supply of devices such as south bridge), the final realization started shooting fully.
Based on the circuit diagram of Fig. 3, each node power of present embodiment has realized sharing, and the change on its electrifying timing sequence is as shown in Figure 4.Wherein SLP_S3# is the S3 state enable signal of being sent by South Bridge chip, is in the S3 sleep state during low level; The PS_PWROK signal is that power supply is exported normal indicator signal.During start, as long as any one node is supressed the start button, the south bridge of respective nodes will send the SLP_S3# signal, changes the 5V enable signal through 12V and makes 12V change the 5V circuit working; After 5V voltage was normal, its controller sent the POWER_GOOD signal and drives DC-DC transfer circuit II work, changes the 3.3V enable signal through 12V and makes 12V change the 3.3V circuit working; After 3.3V voltage is normal, only presses the node of on & off switch and just can export the PS_PWROK signal.The PS_PWROK signal carries out and door with the SLP_S3# signal of pressing the node of on & off switch, and its output signal is controlled powering on of postorder power circuit as the enable signal of postorder power circuit, final realization start fully.
During shutdown, have only when all nodes are all pressed closing key, 12V changes the 5V circuit and 12V commentaries on classics 3.3V circuit just quits work; If otherwise have a node to be in open state, 12V changes the 5V circuit and 12V commentaries on classics 3.3V circuit is just in running order.
