Fig. 2 is a schematic circuit diagram of the power module in this embodiment, in fig. 2, the power module 6 includes a voltage input terminal Vin, a first resistor R1, a first diode D1, a first MOS transistor M1, a first transistor Q1, a second resistor R2, a second transistor Q2, a third resistor R3, a fourth resistor R4, and a voltage output terminal Vo, wherein the voltage input terminal Vin is connected to an anode of the first diode D1, a source of the first MOS transistor M1, and one end of the first resistor R1, a gate of the first MOS transistor M1 is connected to the other end of the first resistor R1 and a collector of the first transistor Q1, a cathode of the first diode D1 is connected to a base of the first transistor Q1, one end of the second resistor R2, and a collector of the second transistor Q2, a drain of the first MOS transistor M1 is connected to one end of the third resistor R3 and one end of the voltage output terminal Vo, and a base of the second transistor Q599, the emitter of the first triode Q1, the other end of the second resistor R2, the emitter of the second triode Q2 and the other end of the fourth resistor R4 are all grounded.

The first diode D1 is a current limiting diode for current limiting protection. The current limiting protection principle is as follows: when the current of the branch in which the first diode D1 is located is large, the current of the branch in which the first diode D1 is located can be reduced by the first diode D1, so that the branch can be kept in a normal operating state, and the components in the circuit cannot be burnt out due to the large current, so that the safety and reliability of the circuit are high.

It should be noted that in the embodiment, the first diode D1 is of a type L-1822, and in practical applications, the first diode D1 may also be of other types having similar functions.

Setting a preset voltage according to the requirement of the MCU1, i.e., adjusting the magnitudes of the third resistor R3 and the fourth resistor R4; then, the proportional relation between the third resistor R3 and the fourth resistor R4 is adjusted, so that when the voltage of the voltage output end Vo is equal to the preset voltage, the second triode Q2 is just conducted; the second transistor Q2 is used as a switch for switching between a regulated state and a conducting state.

When the input voltage of the voltage input end Vin is higher, namely exceeds the preset voltage, the voltage stabilizing state is achieved, the second triode Q2 starts to be conducted, and the input voltage clamp is located at the preset voltage; the base of the first transistor Q1 starts to cut off, that is, the potential of the collector of the first transistor Q1 changes with the potential change fed back by the base of the second transistor Q2, thereby forming a negative feedback control, wherein the feedback voltage rises, even if the gate-source voltage of the gate of the first MOS transistor M1 drops, the output voltage is reduced, and the feedback voltage drops, even if the gate-source voltage of the first MOS transistor M1 rises, the output voltage is increased, so that the output potential is always clamped at the preset voltage.

When the voltage of the voltage input end Vin is lower than the preset voltage, the second triode Q2 is switched off, and the output voltage is almost equal to the input voltage; the first transistor Q1 is turned on, the collector potential of the first transistor Q1 drops to almost ground, the gate-source voltage of the first MOS transistor M1 reaches the maximum value, and the first MOS transistor M1 is completely turned on, so that the input voltage is output to the MCU1 with a negligible voltage drop.

In this embodiment, the first MOS transistor M1 is a P-channel MOS transistor. The first transistor Q1 is an NPN transistor. The second transistor Q2 is an NPN transistor. Certainly, in practical applications, the first MOS transistor M1 may also be an N-channel MOS transistor, and the first transistor Q1 and the second transistor Q2 may also be PNP transistors, but the structure of the circuit is also changed accordingly.

In this embodiment, the power module 6 further includes a first capacitor C1, one end of the first capacitor C1 is connected to the base of the first transistor Q1, and the other end of the first capacitor C1 is connected to the collector of the second transistor Q2. The first capacitor C1 is a coupling capacitor for preventing interference between the first transistor Q1 and the second transistor Q2, so as to further enhance the safety and reliability of the circuit.

It should be noted that, in the present embodiment, the capacitance of the first capacitor C1 is 280 pF. Of course, in practical applications, the capacitance value of the first capacitor C1 may be adjusted accordingly, that is, the capacitance value of the first capacitor C1 may be increased or decreased accordingly.

In a word, in this embodiment, the utility model discloses can change multichannel bluetooth signal into 5G and remove the network signal, it can be applied to various occasions, convenience of customers in a flexible way and remove the use, can satisfy the user demand.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
