Abstract
The invention relates to a charging circuit, in particular to a single-battery mobile phone charger convenient for travelling, which comprises a shell and a single-battery box in the shell. The charger is characterized in that a DC/DC (direct current/direct current) boost circuit board is fixed in the shell; the input end of the DC/DC boost circuit board is electrically connected with the positive electrode and the negative electrode of the single-battery box and the power output end thereof is connected with a USB (universal serial bus) power interface seat; and the DC/DC circuit converts a 1-1.5V single battery into 5V voltage and provides the voltage to a USB conversion interface in the form of constant current. The single-battery mobile phone charger has low cost, is environment-friendly and does not waste resources.
Description
Technical field
The present invention relates to a kind of charging circuit, particularly make things convenient for a kind of single battery charger for mobile phone of out on tours.
Background technology
Existing a kind of charger that passes through four batteries to cell-phone charging because number of batteries is too many, adopts general alkaline battery can only though made things convenient for the user, bring environmental issue with once, the waste resource; Then quantity is many to adopt rechargeable battery, the cost height.
Summary of the invention
The purpose of this invention is to provide low, the environmental protection of a kind of cost, do not waste a kind of single battery charger for mobile phone of resource.
The object of the present invention is achieved like this, a kind of single battery charger for mobile phone, comprise a batteries storehouse in housing, the housing, it is characterized in that: the housing internal fixation has DC/DC booster circuit plate, the input of DC/DC booster circuit plate is electrically connected with the positive and negative electrode in a batteries storehouse, and the power output end of DC/DC booster circuit plate connects USB power interface seat; One batteries converts the monocell of 1-1.5V to 5V voltage by the DC/DC circuit and offers the USB translation interface with constant current.
Described DC/DC booster circuit plate input voltage is 1-6V, and its output voltage is at 5.5-4.5 V.
Be serially connected with the luminous tube circuit between described DC/DC booster circuit plate output and the USB power interface seat.
Advantage of the present invention is: it is by batteries power supply, and a batteries converts the monocell of 1-1.5V to 5V voltage by the DC/DC circuit and offers the USB translation interface with constant current.Rechargeable battery quantity is few like this, and cost is low.Because a batteries is when DC/DC is transformed into 5V, its output current is along with the prolongation in charging interval, and its electric current also can diminish, and reaches because the voltage of load this moment rises, the low fluctuation that the input cell voltage brings that disappeared.
Description of drawings
The invention will be further described below in conjunction with the embodiment accompanying drawing:
The utility model example structure schematic diagram on Fig. 1;
Fig. 2 is an embodiment of the invention circuit theory diagrams.
Among the figure, 1, housing; 2, battery compartment; 3, positive electrode; 4, negative electrode; 5, indicator light; 6, DC/DC booster circuit plate; 7, USB power interface seat; 8, a batteries; 9, mobile phone; 10, conversion line.
Embodiment
As shown in Figure 1, a kind of single battery charger for mobile phone, the DC/DC booster circuit plate 6 that comprises a batteries storehouse 2, housing internal fixation in housing 1, the housing, the input of DC/DC booster circuit plate 6 is electrically connected with the positive electrode 3 in a batteries storehouse 2, negative electrode 4, and the power output end of DC/DC booster circuit plate 6 connects USB power interface seat 7; One batteries 8 converts the single battery voltage of 0.9-2V to 5.5-4.5 V voltage by the DC/DC circuit of DC/DC booster circuit plate 6, and 5.5-4.5 V voltage offers the USB translation interface with constant voltage.When mobile phone 9 connects the USB translation interface by conversion line 10, be charging process, indicator light 5 is bright.Conversion line 10 can be various hands with the standard handovers line of charging usefulness.
As shown in Figure 2, the DC/DC booster circuit of DC/DC booster circuit plate 6 is: the DC/DC IC that boosts, and as RT9266.DC/DC booster circuit plate input voltage is 1-6V, and its output voltage is at 5.5-4.5V.Be serially connected with the luminous tube circuit between DC/DC booster circuit output and the USB power interface seat, the luminous tube circuit comprises a current-limiting resistance and an indicator light 5.The present invention is by batteries power supply, and a batteries converts the monocell of 1-1.5V to 5V voltage by the DC/DC circuit and offers the USB translation interface with constant current.Because a batteries is when DC/DC is transformed into 5V, its output current is along with the prolongation in charging interval, and its electric current also can diminish, and reaches because the voltage of load this moment rises, the low fluctuation that the input cell voltage brings that disappeared.
