  • Self-adaptive constant-current driving circuit and method for three-channel multi-color LED
    Patent number: 12289813
    Abstract: A self-adaptive constant-current driving circuit for a three-channel multi-color LED, including a decoder, a two-phase non-overlapping circuit, and a LED constant-current driving circuit, where the decoder determines the number of lighted channels according to a first input signal, and generates a first switch control signal and a second switch control signal; the two-phase non-overlapping circuit modulates the first switch control signal into a first two-phase non-overlapping signal and a second two-phase non-overlapping signal, and modulates the second switch control signal into a third two-phase non-overlapping signal and a fourth two-phase non-overlapping signal; the LED constant-current driving circuit controls an on/off state of the respective channel of LED according to a second input signal, and outputs a current for controlling a brightness of the respective channel of LED according to the first two-phase non-overlapping signal, the second two-phase non-overlapping signal, the third two-phase non-ove
