  • CONSTANT CURRENT OUTPUT CIRCUIT CONFIGURED FOR MICRO-CURRENT AND MICRO-CURRENT SHOWER HEAD
    Publication number: 20230275574
    Abstract: A constant current output circuit configured for a micro-current comprises a voltage boosting module and a logic controller. An input terminal of the voltage boosting module is connected to a power source, and an output terminal of the logic controller is connected to the input terminal of the voltage boosting module. The logic controller is configured to compare a sample voltage generated by the micro-current on a sampling resistor with a first threshold voltage, and when the sample voltage is less than the first threshold voltage, the logic controller drives the voltage boosting module to boost an output voltage until the sample voltage is increased to be greater than the first threshold voltage.
