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: lo_set=(DT/T)lo_norm Where, lo_set for the desired output current value (mA), D for the PWM signal duty cycle (%), T for the period of the PWM signal (S), lo_norm for the rated output of the driver (mA). Caution: The above formula is for reference only, the output current may deviate because of the different loads, the PWM signal can not be less than 0.7ms on-time limit, otherwise the product can not work properly, if you hear a slight sound from the driver when PWM dimming is a normal phenomenon, because the PWM dimming frequency in the range of human ear hearing.
