Requirement of these mobile electronic terminals to its battery durable ability also more and more higher.And the most straight of battery durable ability is lifted at present
It is exactly to increase battery electric quantity to connect effective method.
With the continuous lifting of battery electric quantity, the thing followed is requirement to charging rate also more and more higher.Thus,
Various rapid nitridings arise at the historic moment.The simplest understanding of quick charge is exactly the charging rate for accelerating battery, and is charged
The lifting of speed, is realized by lifting the input power for charging.But the electricity that data wire generally used now can be carried
Stream is limited, it is impossible to simply improve the input power of charging by increasing electric current.So, industry employs raising charging voltage
Method improve the input power of charging.
By the charging voltage that rapid nitriding is used is different from traditional charging scheme, therefore, skill is filled soon using
In the electronic equipment of art, for example：Portable power source, mobile phone etc., can be monitored using the protocol chip of quick charge or control to charge
The charge parameter of equipment, charging equipment.
Such as in the charging scheme that high pass is provided, it is desirable to which the charging voltage voltage of input and output must be in 5V to 12V
Between.And it is required that the input of charging circuit must not only possess association using the protocol chip of high pass, the protocol chip of high pass
View function is also equipped with buck functionality, i.e. the voltage of input is typically all again to the battery of charging equipment after being depressurized
Group charges.
By taking compact power as an example, it means that the battery voltage in compact power can only be lower than 5V.But,
When compact power charges to other charging equipments, in order to meet the requirement of quick charge, the voltage of its output needs again

Less than 5V, with existing battery core in the market for, can only be powered using single battery, it is assumed that specific battery core voltage is
3V, then the electric current of battery pack output is 8A, that is to say, that circuital current maximum between battery pack to booster circuit can be with
Reach 8A.It is well known that bigger its loss of electric current is also bigger in circuit, the caloric value of circuit is also higher.
Therefore, in foregoing circuit framework, the charging voltage of output is higher needed for compact power, and the loss in circuit will
Bigger, circuit caloric value also can be higher, and thus, it is too small that product is unfit to do, and can otherwise produce the bad problem of heat dispersion, but
It is that the volume size of product can directly affect the portability that expires.
【The content of the invention】
The technical problem to be solved in the present invention is to provide a kind of the portable of the quick charge that caloric value is smaller, loss is relatively low
Power supply.
In order to solve the above technical problems, the present invention provides following technical scheme：
A kind of compact power, possesses quick-charge function, and it includes：Input is connect, and input protocol chip, buck is filled
Circuit, battery pack fills identification chip and output end interface soon；Wherein：The input interface, for realizing being electrically connected with charger
Connect；The input protocol chip, for being communicated with the charger by the input interface, determines that the charger is provided defeated
Enter charge parameter and meet fast charge protocol；The buck controls circuit, possesses Bidirectional up-down pressure charging/discharging function, for this
Charged to the battery pack after the input voltage of charger is boosted or step-down is processed；Or, fill identification chip soon according to this anti-
The output charge parameter of feedback, is treated after the output voltage to the battery pack carries out buck treatment by the output interface
Charging equipment charges；This fills identification chip soon, and Handshake Protocol communication is carried out with the charging equipment for being connect by the output, knows
Whether the charging equipment is not fast charge mode, and confirms the output charge parameter provided needed for the battery pack, and should
Output charge parameter feeds back to buck charging circuit；The output interface, for realizing electrically connecting with the charging equipment.
The beneficial effects of the present invention are the charging circuit of use possesses Bidirectional up-down pressure function so that the portable shifting
The voltage of battery pack in dynamic power supply, just without by fast charge protocol, the input of definition and the voltage of output end
Limitation, and can be to design battery voltage according to the actual requirements, so as to reduce the electric current between battery pack and charging circuit, drop
Low circuit is lost and caloric value, lifts the conversion ratio of circuit.
