Embodiment one

Fig. 2 is refer to, the embodiment of the present application provides a kind of power-supply management system, applied to just like notebook computer, flat In the portable electronic equipment such as plate computer, the electronic equipment has a power supply adaptor 100, and the electronic equipment bag A battery is included, is specifically as follows a rechargeable battery, the system includes：

One charging management chip 101, model can be MAX1645B, MAX1908 etc., can be with the power supply adaptor 100 connections；

One cpu power managing chip 102, model can be ADP3198, ADP3188 etc., with the charging management chip 101 connections；

One PMU chips 103, it is connected with the charging management chip 101；

Wherein, when the power supply adaptor 100 is connected to the electronic equipment, the charging management chip 101 is by institute The first output voltage for stating the output of power supply adaptor 100 is converted to second output voltage different from first output voltage, And export second output voltage to the battery 104, the CPU managing chips 102 and the PMU chips 103, its In, second output voltage is converted to three different from second output voltage by the cpu power managing chip 102 Output voltage, and export to the CPU105 of the electronic equipment；The PMU chips 103 are converted to second output voltage The N-1 different from second output voltage the 4th output voltages, think in the electronic equipment except the CPU105 with Outer other power consuming devices power supply 106, wherein N are the integer more than or equal to 2.

During specific implementation, when the electronic equipment is not using power supply adaptor power supply, and battery electric quantity fills When sufficient, cpu power pipe can be made directly by cpu power managing chip and PMU chip power supplies that battery is electronic equipment internal It is suitable supply voltage that chip and PMU chips, which are managed, by the voltage conversion of battery, thinks that the power consuming device of electronic equipment internal supplies Electricity.

The power supply source of people's daily life is generally civil power, and different national line voltages is also different, global civil power electricity It is pressed between 110V~240V, and the line voltage in China is then 220V, so high voltage is not suitable for electronic equipment, And the effect of power supply adaptor is exactly the voltage that civil power is converted to relatively low suitable electronic equipment and used.Power supply adaptor is small The power supply conversion equipment of type portable electric appts, is typically made up of shell, power transformer and rectification circuit, defeated by its Exchange output type and direct-current-output type can be divided into by going out type；It can be divided into Direct Plug-In and Table top type by connected mode.With notebook electricity Exemplified by brain, the power supply adaptor of most notebook computers can be suitable for 100V~240V alternating currents（50/60Hz）, notebook The power supply adaptor of computer is according to the difference of model, and for the voltage of output between 16V~20V, 19V and 20V situation are in the majority.Electricity Transformer and rectification circuit in source adapter, civil power is converted to the low-voltage DC of suitable computer work.

By taking notebook computer as an example, its internal device has corresponding operating voltage requirements according to its different function. For example, the nominal charging voltage of battery is 11V~19V；The input voltage of charging management chip typically in below 30V, here with Exemplified by model MAX1908 charging management chip, input voltage during its normal work is between 8V-25V, maximum input electricity Press as 28V, civil power is converted to the first relatively low output voltage and exported to charging management chip by power supply adaptor, so that charging valve Managing chip being capable of normal work；Again because cpu power managing chip is according to its own model, also should mutually there is its suitable normal work Voltage requirements, specifically, by taking model ADP3198 cpu power managing chip as an example, the input voltage that it is supported is 12V, The first output voltage that charging management chip exports power supply adaptor is converted to the work electricity of suitable cpu power managing chip Pressure, such as 12V, the first output voltage is converted to the voltage of suitable electronic equipment CPU work by cpu power managing chip, and is It is powered.Such as present notebook computer uses Intel platforms more, and CPU uses Intel processor more, model ADP3198's Cpu power managing chip can be converted to 12V electric power output voltage the core supply voltage needed for Intel processor.Together Reason, PMU chips also have the input voltage demand for being suitable for its normal work, it can be seen from the structure of power-supply management system, PMU cores The input voltage of piece and cpu power managing chip is identical.

It is other all power consumption function element power supplies in addition to CPU in electronic equipment to be used for due to PMU chips, it is seen that PMU units are most important for the power management of portable electric appts.Below to the PMU chips of power-supply management system Structure and operation principle are described in detail.

First, in the structure of PMU chips, Fig. 3 is refer to, the PMU chips 103 include：N number of power module（301~ 310, in the embodiment of the present application so that N takes 10 as an example）With a bus control module 311；Wherein, the bus control module 311 with N number of power module（301~310）In N-1 power module（302~310）Connection, the bus marco mould Block 311 sends a control signal to the N-1 power module（302~310）, so that the N-1 power module（302~ 310）Power management operations are carried out based on the control signal.

Specifically, in the present embodiment, the power module of PMU chip internals includes Switching Power Supply and the class of linear power supply two.

（1）Linear power supply is that alternating current first is reduced into voltage magnitude by transformer, then after rectifier circuit rectifies, is obtained To pulse direct current, the DC voltage with small ripple voltage is obtained by filtering.Reach high-precision DC voltage, must Voltage stabilizing must be carried out by mu balanced circuit；The course of work of linear power supply major loop is that input power is first carried out just through pre- mu balanced circuit After walking AC voltage-stabilizing, dc source is transformed into by main Working transformer isolation rectification, then by control circuit and the micro- place of monolithic Manage and Serial regulation element is fine-tuned under the intelligent control of controller, be allowed to export high-precision direct voltage source.

（2）Switching Power Supply is to utilize modern power electronics technology, the time ratio that controlling switch pipe turns on and off, and is maintained A kind of power supply of regulated output voltage.Switching Power Supply is typically by pulse width modulation（PWM）Control IC and FET （MOSFET）Form.Switching Power Supply is because power transistor is operated on off state, so the small power consumption on transistor, conversion effect Rate is high, and generally 60~70%.
