More Information
Summary:The utility model provides a constant-voltage constant-current compensation circuit and electronic equipment, which are characterized in that the input end of a power conversion module receives a first feedback signal, and the output end of the power conversion module outputs power supply voltage and power supply current; the first optocoupler module is coupled to the output end of the power conversion module and outputs a first feedback signal; the compensation selection module is coupled to the first optocoupler module through the compensation module and further receives the power supply voltage and the power supply current, and the control end of the compensation selection module receives a mode switching signal. The constant-voltage constant-current control module is respectively coupled to the first optocoupler module and the compensation selection module, and is also respectively used for receiving the power supply voltage, the power supply current, the set voltage and the set current so as to output a
