SINGLE CHIP LED DRIVER CIRCUIT

원문 (중국어)

A light-emitting diode (LED) driver circuit for driving an LED and electrically connectable to an activation interface. The LED driver circuit may include a controller, a binary counter, a digital-to-analog converter (DAC), and a voltage controller current source (VCCS). The controller may receive an activation signal from the activation interface and generate a control signal. The binary counter may be electrically connected to the controller and receive the control signal from the controller and generate a code. The DAC may be electrically connected to the binary counter and receive the code from the binary counter and generate an analog signal. The VCCS may be electrically connected to the DAC, receive the analog signal from the DAC, and control a brightness of the LED based on the analog signal.
