PWM | Dimming control signal (2.8V-6V on) | ||
Note: The signal must be connected to a common ground reference, otherwise the signal is unstable | |||
For a certain frequency of PWM dimming, the output current of the driver has a certain relationship with the duty cycle of the PWM signal, the calculation method refers to this formula:
