Color LED driving circuit and color controller

The present application provides a color LED driving circuit, which comprises a set of switches and a color controller. The switch assembly has a first switch and a second switch, respectively having a first terminal, a second terminal and a control terminal. The first terminal of the first switch is configured to be coupled to a first LED load, and the first terminal of the second switch is configured to be coupled to a second LED load. The color controller comprises a first controller and a second controller. A ground terminal of the first controller is coupled to ground. The first controller is used to generate an output signal according to a PWM signal, and transmit the output signal to the second controller. The second controller is used to generate a first driving signal and a second driving signal according to the output signal, and output the first driving signal and the second driving signal to the control terminals of the first switch and the second switch through a first driving terminal and a second driving terminal, respectively. A reference terminal of the second controller is coupled to the second terminal of the first switch and the second terminal of the second switch, and potential of the reference terminal is different from a potential of the ground terminal of the first controller.
