AI Technical Summary
Technical Problem
Existing power supplies can only be fixedly connected to one load, making it impossible to freely switch between multiple loads, resulting in high equipment costs.
Method used
Design a power switching output circuit, including a load signal buffer circuit, a judgment module and a power switching module. By receiving and processing load request signals, it generates effective control signals to realize the switching connection between the power supply and multiple loads.
Benefits of technology
It enables a single power supply to freely switch between multiple loads, reducing the overall cost of the equipment.

Abstract
The application discloses a power switching output circuit and an output method. The power switching output circuit comprises a load signal buffer circuit, a judging module and a power switching module; the load signal buffer circuit is used for receiving each load request signal output by a control circuit of >=2 loads, and generating an enabling signal of each load according to each load request signal; the judging module is used for receiving the enabling signal of each load, performing operation on the enabling signal of each load, and outputting an effective control signal corresponding to a load to be switched on by a power supply; and the power switching module is used for receiving the effective control signal and switching the connection between the power supply and the load according to the effective control signal. The above scheme can determine the effective control signal through the judging module according to the request signal sent by the load, and then realize power switching through the power switching module according to the effective control signal, so that one power supply can switch the output of multiple loads, and the total cost of equipment is reduced.
