It is appreciated that because the composition structure of VRM Voltage Regulator Module is different, so being realized by the VRM Voltage Regulator Module
Also can be different to the regulative mode of the output end voltage value of charger, and the composition structure of VRM Voltage Regulator Module has a lot, below
The example of the composition structure of two kinds of different VRM Voltage Regulator Modules will be provided：
As a kind of example, the VRM Voltage Regulator Module is DC-DC modular converters.Wherein, as shown in Fig. 2 DC-DC moduluss of conversion
The electrode input end of block 110 is connected with the output end of charger 10, and the cathode output end of DC-DC modular converters 110 and movement are whole
The input of the charging circuit 21 at end 20 is connected.That is, in mobile terminal 20 in addition to having conventional charging circuit 21,
Also include DC-DC module 110, the DC-DC module can be located at the front end of charging circuit 21, to detect the charger 10 of insertion
Output end voltage value.
In this example, whether the output end voltage value that charger can be detected by DC-DC modular converters exceedes default threshold
Value.When the output end voltage value of charger exceedes predetermined threshold value, the charger that be able to will be received by the DC-DC modular converters
Output end voltage value carry out reduced pressure operation, the output end voltage value of charger is reduced to target voltage values, that is, cause DC-
The magnitude of voltage of the output of DC modular converters is target voltage values.
It is appreciated that due to law of conservation of energy, so in the output end voltage by DC-DC modular converters to charger
When value carries out decompression processing, the output end current value of the charger should increase in theory, and in order to ensure the normal of mobile terminal
Charging, also need to control charging current in the critical field that can be born when mobile terminal charges.
Therefore, in pressure reduction is carried out to the output end voltage value of charger by DC-DC modular converters, also need pair
The output current of DC-DC modular converters is adjusted.Further, by VRM Voltage Regulator Module according to predetermined threshold value to charging
After the output end voltage value of device is adjusted to generate target voltage values, the charging method of the mobile terminal may also include following
Step：
111) the output end current value of charger can be gathered；
For example, the output end current value of charger can be gathered by DC-DC modular converters.
112) it is theoretical according to the output end voltage value, output end current value and target voltage values calculating current of charger
Value；
Specifically, can according to law of conservation of energy, according to the output end voltage value of charger, output end current value and
Target voltage values (i.e. the output voltage of DC-DC modular converters), calculate the output current theoretical value of DC-DC modular converters (i.e.
Above-mentioned electric current theoretical value).For example, it is assumed that the output end voltage value of charger is 9V, the output end current value of charger is 1A,
Target voltage values are 5V, then according to law of conservation of energy, can calculate after DC-DC modular converters, and electric current theoretical value should
It is raised to 9/5*1A=1.8A.
113) judge whether electric current theoretical value matches with charging current standard value；
Wherein, in an embodiment of the present invention, when the charging current standard value can be regarded as mobile terminal charging, configuration
The normalized current that charging current value, i.e. mobile terminal can be born when charging.For example, the charging current standard value can be
1.5A。
That is, after electric current theoretical value is calculated, the electric current theoretical value and charging current standard value can be carried out
Size contrasts, if the electric current theoretical value and charging current standard value is equal in magnitude, can determine that the electric current theoretical value with filling
Electric current standard value matching, can not now any processing be carried out to the charging current value, but it is directly that the charging current value is defeated
Go out the charging circuit to mobile terminal, to realize the charging to mobile terminal；If the electric current theoretical value is more than the charging current
Standard value, then it can determine that electric current theoretical value mismatches with charging current standard value.
If 114) electric current theoretical value mismatches with charging current standard value, the work ginseng of adjustment DC-DC modular converters
Number, so that the charging circuit of mobile terminal charges according to charging current standard value to mobile terminal.
Specifically, when electric current theoretical value and charging current standard value mismatch, it can adjust the work of DC-DC modular converters
Parameter, for example, can DC-DC modular converters working frequency, so that the output current value of DC-DC modular converters to be adjusted to indirectly
Suitable charging current standard value.
As another example, the VRM Voltage Regulator Module may include analog to digital conversion ADC detection circuits and bleeder circuit.Its
In, as shown in figure 3, one end of ADC detection circuits 120 is connected with the output end of charger 10, one end of bleeder circuit 130 is with filling
The output end of electrical equipment is connected, and the other end of bleeder circuit 130 is connected with the input of the charging circuit 21 of mobile terminal 20.
That is, as shown in figure 3, one end of ADC detection circuits 120 can be with the power management chip in mobile terminal
(Power Management Integrated Circuits, referred to as PMIC) 23 one end is connected, ADC detection circuits 120
The other end be connected with the output end of charger 10, PMIC 23 other end is connected with the master chip 22 in mobile terminal 20, point
One end of volt circuit 130 is connected with the output end of charger 10, the other end and the charging in mobile terminal 20 of bleeder circuit 130
Circuit 21 is connected, and the another end of bleeder circuit 130 is connected with the master chip 22 in mobile terminal 20.Wherein, in this example, divide
Volt circuit 130 can include fixed resistance and variable resistor, wherein, the variable resistor can be connected with the master chip in mobile terminal,
To receive the change in resistance instruction of master chip transmission, to realize the change to itself resistance.
In this example, whether the output end voltage value that electric circuit inspection charger can be detected by analog to digital conversion ADC exceedes
Predetermined threshold value., can be according to the output end voltage value of charger, default when the output end voltage value of charger exceedes predetermined threshold value
The configuration resistance of the computing the resistor value variable resistor of threshold value and fixed resistance, and according to the configuration resistance of variable resistor to variable
The resistance of resistance is adjusted, so that the magnitude of voltage of the other end output of bleeder circuit is target voltage values.
Specifically, the output end voltage value of circuit collection charger is being detected by connecting the ADC of power management chip,
, can be according to the computation model in bleeder circuit, according to filling when detecting that the output end voltage value of the charger exceedes predetermined threshold value
The computing the resistor value of the output end voltage value of electrical equipment, predetermined threshold value and fixed resistance goes out the configuration of variable resistor in bleeder circuit
Resistance, then, the resistance of the variable resistor can be adjusted according to the configuration resistance of variable resistor, so as to obtain the electricity of bleeder circuit output
The control of pressure value is target voltage values.Wherein, in an embodiment of the present invention, above-mentioned computation model can be as follows：
Vout=Vin*R1/ (R1+R2) (1)
Wherein, Vout gives the signal of charging circuit (i.e. target voltage values) to go out by bleeder circuit partial pressure for exporting,
For example, Vout can be 5V；Vin is the output voltage values (such as 9V) that ADC detects the charger that circuit sampling arrives；R1 is bleeder circuit
In variable resistor；R2 is the fixed resistance in bleeder circuit.Thus, variable resistor R1 needs can be derived from by formula (1)
The size being configured.
It is worth noting that, in an embodiment of the present invention, above-mentioned target voltage values need to be more than or equal to predetermined threshold value, and
Difference between target voltage values and predetermined threshold value is within a preset range.Because because Vin input is probably one non-
Fixed signal, for example, it may be possible to be 8.9V, it is also possible to 9.1V, or just 9.0V.So corresponding variable resistor R1 is also one
The value of individual change.And the control signal provided for the master chip in mobile terminal possibly can not be such that Vout just falls in default threshold
In value, for example, 5V, but under actual conditions, even charging circuit 5.1V, 5.2V, or even the 5.5V of mobile terminal do not have
It is problematic, as long as taking one higher than predetermined threshold value (such as 5V) but closest to the value can of predetermined threshold value (such as 5V).Also
It is to say, for example, it is assumed that the value that R1 needs to take is 10kohm, but 10kohm can not be fetched directly into, immediate from it
Two values that can be taken are 9kohm and 11kohm respectively, then we just take 11kohm, and such Vout value can be bigger than original 5V
10%, that is, 5.5V.
Finally, after the configuration resistance of variable resistor is calculated, the master chip control access point of mobile terminal can be passed through
The variable resistor resistance of volt circuit, most suitable resistance is selected according to actual conditions to realize so that be flowed into charging circuit
Magnitude of voltage meet the charging requirement of mobile terminal, to enable mobile terminal to charge normal.Wherein, in the implementation of the present invention
In example, the variable resistor can be digital current potential resistance chip.
S130, mobile terminal is charged according to target voltage values by the charging circuit of mobile terminal.
Specifically, after by VRM Voltage Regulator Module by the output end voltage value regulation of charger to target voltage values,
The charging voltage for flowing into charging circuit is target voltage values, now can by charging circuit according to target voltage values come pair
Mobile terminal is charged, to ensure that mobile terminal can charge normal.
Whether the charging method of mobile terminal according to embodiments of the present invention, the output end voltage value of detectable charger surpass
Predetermined threshold value is crossed, if exceeding, the output end voltage value of charger is adjusted according to predetermined threshold value by VRM Voltage Regulator Module
Section is charged by the charging circuit of mobile terminal with generating target voltage values according to target voltage values to mobile terminal.
The charge voltage range that can be born the output end voltage control of charger in mobile terminal by VRM Voltage Regulator Module,
Only need to setting VRM Voltage Regulator Module that any charger can be achieved in mobile terminal, (such as standard configuration or non-standard charger are nonstandard
Charger with charger parameter) charged for mobile terminal, charging cost is reduced, improves user's charger on hand
Utilization rate, the serious forgiveness using different chargers is improved, and improved using the security that charger is mobile terminal charging.

Cathode voltage value, and judge whether the cathode voltage value on the charging wire exceedes predetermined threshold value, if the positive pole on the charging wire
Magnitude of voltage exceedes predetermined threshold value, then can determine that the output end voltage value for the charger 10 being connected with the charging wire has exceeded default threshold
Value.For example, the output end voltage value of the charger 10 is 9V, and predetermined threshold value 5V, then the detectable connection of VRM Voltage Regulator Module 100
Cathode voltage value on to the charging wire of mobile terminal 20 is 9V, and the value has exceeded predetermined threshold value 5V, then can determine that the charging
The output end voltage value of device 10 has exceeded predetermined threshold value.
It should be noted that in an embodiment of the present invention, when the cathode voltage value on the charging wire is not less than default threshold
