Typical application circuit
Application circuits in series
Application circuits in series and parall
1. If the product is applied to high voltage condition (higher than 40V),
the input terminal must be provided with an additional capa-
citor
(≥47µF/100V) to prevent voltage spike from damaging the module.
2. The output cathode cannot be connected with the input grounding,
or
it will damage the module.

Where, Io_set represents required output current (mA); D represents the
duty ratio (%) of PWM signal; T represents the period (ms) of PWM sig-
nal; and Io_norm represents the rated output value (mA) of the driver.
Note: The above formula is for reference only; and deviation of output is normal since the PWM dimming frequency is within the auditory fre-
current may exist due to various loads. The min. conducted time of PWM
quency range of human ears (20Hz-20KHz in general). To prevent seeing
signal shall not be less than 0.75ms, or the product will be in abnormal flash of the LED by human eyes, it is suggested to set the PWM dimming
operation; in case of low voice from the driver during PWM dimming, it frequency between 100-200Hz.

The voltage drop of all LEDs in the datasheet is 3.3-3.8V during actual
application, the number of LEDs can be confirmed based on the actual
voltage drop and output voltage of LEDs.
This product does not support hot-Plug use.
