Description
Technical field
Electronic technology field is the utility model is related to, specially a kind of single MCU realizes the portable power source of synchronous rectified boost.
Background technology
Nowadays the portable type electronic product such as electricity such as tablet personal computer, notebook computer, smart mobile phone, digital camera, video camera
Sub- equipment is more and more, requirement of the people to this electronic power cruising time also more and more higher, but the original of these equipment at present
Packed battery all can it is low because of battery capacity, cruising time is short, can not meet people in going on business or travelling to these equipment electricity consumptions
Demand.Just because of this, portable power source arises at the historic moment.Portable power source typically all using rechargeable battery as power source, by
In rechargeable battery have can Reusability the characteristics of, so it not only saves resource, also subtracted compared with non-charging dry battery
The pollution to environment is lacked, still, the output current of in general portable power source is uncontrollable at present, so will cause as follows
Influence:1st, when the output current of portable power source is more than the maximum charging current of electronic product, excessive electric current can produce to electronics
Product damage；2nd, when the output current of portable power source is less than the maximum charging current of electronic product, charger is in trickle
Charged state, it is necessary to expend is lot more time to battery is fully charged, loses time.Therefore, existing portable power source is present defeated
Go out the defects of charging voltage and current is unadjustable.
Utility model content
The shortcomings that in order to overcome prior art to refer to, the utility model provide a kind of single MCU and realize synchronous rectified boost
Portable power source.
The utility model solve technical scheme that its technical problem uses for：A kind of single MCU realizes synchronous rectified boost
Portable power source, including MCU (micro-control unit), rechargeable battery, charging input end mouth, charging input circuit module, charging output
Port, charging output circuit module, battery protecting circuit module, rectification boosting circuit module and key controlled unit, it is described to fill
Described in electrical input mouth passes sequentially through rectification boosting circuit module, charging input circuit module connects with battery protecting circuit module
Rechargeable battery, the charging output port pass sequentially through rectification boosting circuit module, output circuit module and battery protecting circuit
Module connects the rechargeable battery, and the MCU data connect the rectification boosting circuit module and key controlled unit, pass through institute
Key controlled unit input control instruction is stated, the MCU data control the rectification boosting circuit module to input the charging
The input voltage of the input voltage of port and the charging output port synchronizes rectifier boost so that portable power source can root
According to the situation that is actually needed, fast charge is completed.
Wherein, the rechargeable battery uses lithium battery group, and the charging input end mouth and charging output port use USB
Type-C interfaces.
The battery protecting circuit module includes carrying out under-voltage protection, overcurrent protection and short circuit to the rechargeable battery
Low voltage protection circuit, circuit overcurrent protection and the short-circuit protection circuit of protection.
The beneficial effects of the utility model are：The portable power source of the design, its working condition can be according to key controlled units
It is adjusted, when being charged to portable power source, controllable rectification boosting circuit module does not work, and carries out trickle charge to it, also may be used
Rectification boosting circuit module is controlled to reach fast charge purpose to pressure-increasning state；Similarly, other electronics are produced using portable power source
When product are charged, adjustable to fast charge pattern, the maximum charging voltage of the electronic product to be charged with reference to needs is to portable power source
Output voltage be adjusted, electronic product will not be damaged because charging current is excessive, so as to save the time.When with
When family possesses enough charging intervals, moreover it is possible to battery is charged or used in a manner of trickle charge, so as to be produced to battery and other electronics
Product make more excellent protection.
