Description
Field that the present invention belongs to:
The present invention relates to the voltage regulator field, relate in particular to the voltage regulator of computer system.
Background technology:
Computer system generally contains many integrated circuits (IC).Most of IC as microprocessor, has specific power and voltage request.When IC of design, the specification requirement that the circuit board of above-mentioned ICs is housed also will be limited to be fit to power and the voltage request of these ICs.In the IC design, a variation is arranged, when requiring to redefine a specific voltage or power, can produce difficulty.All very general when wishing upgrading behind test phase that this still produces and the finished product during design, manufacturing.
In these cases, generally adopt two kinds of methods.One is to redesign circuit board fully to be fit to voltage and the power requirement of new IC.This method general cost is very high and be reluctant usefulness, has especially designed and has manufactured when satisfying former specification requirement when a large amount of circuit boards.Second method is circuit board of design, and it has the flexibility that several ICs that different capacity and voltage request are arranged are fit to.From economic angle, this method is more desirable, but from design angle, it is also difficult more.
Existing several trials design a circuit board, and to the special ICs on the plank, it can provide different adjusting power and voltage.A kind of method is by plate (On-circuit board) voltage regulator and flexible motherboard are realized altogether.The design of plate adjuster and flexible motherboard allows the preset level of system is re-set as the new level of special IC altogether.It is finished by the special-purpose circuit of a cover on the motherboard.For the desired voltage of each assembly in the change system, this circuit is adjustable.
Yet the voltage and the power that are provided by common plate voltage regulator and movable motherboard are subjected to the restriction that their designs define.For improving the flexibility of board design to greatest extent, adjuster and circuit board will provide thorough solution, also are the most expensive solutions usually.Therefore, if 10% being made up of the microprocessor that needs special voltage to regulate of production line, manufacturer will provide the solution of special voltage adjusting to any one circuit board.Its manufacturer wishes circuit board with a standard to its all over products, and this is necessary.When a system did not need to use expensive special solution, above-mentioned solution belonged to waste.On the other hand, if do not provide so thorough solution and plate special circuit can not satisfy the special voltage and the power requirement of system in the design by adjusting, then plate voltage regulator or movable motherboard are just of no use altogether, the circuit board of just having to redesign.
Except will be for plank provides thorough solution, plate voltage regulator and movable motherboard have the shortcoming that can not regulate employed power or range of tolerable variance altogether.For example, a plank that is set at 3.0 ± 10% volts of supplies can be reconfigured to 3.1 ± 10% volts.Yet this plank can not be re-set as supplies with 3.0 ± 5% volts, or regulates 4 amperes of transmission, is designed to transmit 3 amperes if make at first.In other words, if the tolerance of an IC or power requirement have changed in the past, then this circuit board will redesign.
Another kind make circuit board more flexibly method be by chip (on-chip) design of Regulator altogether.The chip design of Regulator is with a voltage regulator and integrated being packaged together of IC altogether, regulates with (on-package) on the same group that this IC is provided power supply and voltage.Because of voltage and the power adjustments of this IC is to carry out in same encapsulation, thereby do not need circuit board done to change just to realize a IC with different voltages or power requirement.
A major defect of chip voltage adjuster is a thermal insulation altogether.Because of voltage regulator modules and IC component package be in the same place, from very near, the thermal diffusion of each assembly influences the combination property of whole unit.Thermal insulation has limited the gross power that two parts assembly consumes.Link to each other with the thermal insulation problem, heat radiation has occupied the major part of available encapsulated space in the common chip voltage adjuster.This has reduced the free space of adjusting part, and requires the voltage regulator modules integrated horizontal to want high, thereby expense is big.
Therefore, expect a cost-effective power adjustments equipment, it can be to specific voltage and the power of assembly transmission specific on the circuit board.The present invention has overcome the defective of prior art, when the assembly on the circuit board requires different power or voltage, can remove a removable power supply trim from motherboard, replaces it with second removable power supply trim.The present invention has used such design, will be a position on circuit board with removable power supply adjusting part, and it can maximum utilize the advantage of this position to minimize thermal diffusion effect simultaneously.
Brief summary of the invention:
A kind of device of regulating power and voltage that provides to circuit board assemblies is provided.
In a specific embodiment, the present invention includes a removable power supply conditioning equipment, its adjusting power and voltage are to predeterminated level.Power adjustment equipment links to each other with computer system by a socket connector.When hope is transported to power on the circuit board assemblies and voltage when changing, initial power adjustment equipment is removed from socket connector, replaces the second power supply conditioning equipment that different capacity and voltage can be provided then.
The present invention provides many-valued voltage and power for the IC assembly that is operated in many-valued voltage and power.The present invention also provides the system that uses a plurality of ICs, and these ICs are operated in them and require under the different voltages and power of voltage.
According to the present invention, voltage regulator can be positioned at the institute very near position of adjusting part, does not occupy domain valuable on the circuit board.Thereby obtain accurate circuit tolerance by the loss the present invention between the assembly that minimizes voltage regulator and its driving.Design of the present invention has also minimized the thermal diffusion effect of voltage modulator circuit.
