Formula for output current:
I
o,set
=
(DT-0.8)
T
I
o,nom
I
o,set
refers to the expected output current value.
I
o,norm
refers to the rated output current
D refers to the pulse width of the PWM signal
T refers to the cycle of the PWM signal
Note: This formula is only supplied as a reference and the output current may be deviated from for different load conditions. The Ton(min) of PWM signal must
be greater than 0.8ms, otherwise the driver cannot be operated normally. It is natural for the driver to generate audible noise during dimming process
because the frequency of the control circuit is within human audible range (20Hz~20kHz). In order to make the LED
fl
ashes not visible to human eye, the
PWM dimming frequency is recommended to be set above 100Hz. PWM curve (Vin=24 V, 5 LEDs)
