Problems solved by technology

[0002] At present, the power supply on the existing market has the problem of a single power supply specification. When a power supply needs to supply power to multiple charging loads, there is a problem that it cannot accurately adapt the loads with different charging parameters, making the power supply of the power supply The efficiency is low and it is impossible to realize the on-demand charging function of one power supply and multiple loads at the same time

Embodiment 1

[0023] refer to figure 1 As shown, a power supply circuit with a communication protocol includes: a PD power interface, the PD power interface is used to electrically connect the PD power supply 1; a step-down module 2, the input end of the step-down module 2 is connected to the PD power interface; load interface, the load interface is connected to the output end of the step-down module 2, and the load interface is used to connect the charging load 3; MCU 4, the MCU 4 is connected to the step-down module 2 in communication ; the first protocol chip 5, the first protocol chip 5 is connected between the load interface and the MCU 4; the second protocol chip 6, the second protocol chip 6 is connected to the PD power interface and the between the above MCU 4. Among them, the voltage step-down module 2 converts the output voltage of the PD power supply 1 into the charging voltage required by the corresponding load 3, the first protocol chip 5 is used to provide the communication c...

Embodiment 2

[0032] The difference between this embodiment and Embodiment 1 is that, referring to figure 2 As shown, the number of charging loads 3 is greater than two, so the number of step-down modules 2 and the number of first protocol chips 5 also increase as the number of charging loads 3 increases.

[0033] refer to figure 2 As shown, in the present invention, the input port of a single step-down module 2 is 1, and the output port is 2, therefore, when the charging load 3 quantity is greater than 2, the quantity of step-down module 2 also increases thereupon;

[0034] Wherein, it should be noted that if the number of output ports of a single step-down module 2 is greater than the sum of charging loads 3 , only one step-down module 2 is required.

[0035]When different charging loads 3 are connected to the load interface, since the MCU 4 module detects the working status of the load interface in real time, the first protocol chip 5 reads the charging parameters required by the corr...
