patent abstract shows that the present invention provides a MiniLED driver chip with internal integrated constant current circuit and digital decoding control circuit, which belongs to the field of MiniLED technology. The driver chip is internally integrated with: a frequency multiplier circuit for amplifying the received low-frequency clock signal; a digital decoding control circuit for digitally logically processing the clock signal after frequency multiplication and the input dimming signal and transmitting the processed signal to the PWM dimming circuit; a PWM dimming circuit for controlling the output current of the constant-current circuit based on the digital signal sent by the digital decoding control circuit; an output terminal of the constant-current circuit for controlling the current input to the MiniLED to remain constant; an MCU controller for adjusting the constant-current circuit based on the MiniLED voltage feedback sent by the led interface circuit; and an over-temperature protection circuit for controlling the led based on the electrical signal sent by the over-temperature protection circuit.The operating state of the interface circuit. Improved the comprehensive control capability of the MiniLED driver chip.
