Where lo_set is the current value(mA) you want to output， Dis the duty cycle(%) of the PWM signal， Tis the period (S) of the PWM signal， and lo_norm is the rated output value(mA) of the driver

note：
The above formula is for reference only.The output current may have deviations due to different loads.The minimum PWM signal conduction time can not be less than 0.7mS， otherwise the product will not work properly.If you hear a slight sound from the driver during PWM dimming Normal phenomenon， because the PWM dimming frequency is within the hearing range of the human ear(generally 20HZ~20KHZ)
