According to
BlackBuck 8M - 8A Buck Laser Driver - NDB7A75, NUBM44, NUMB05, NUBM06, NUBM08 | eBay
On picture with tag "The connection method if you are not using external modulation sources"
on laser diode or LED must be 2...5 V forward voltage
but I received around 10,5V

also I try connect like tag "The connection method using an external signal"
I have an arduino as PWM/TTL
Frequency around 1,95 kHz
Duty cycle from 35% on 1% power in arduino to around 95% on 99% power in arduino
but on LED i still receiving around 10,5V
I also try like this

with potentiometer but also unsuccessfully
Arduino with this cheaper chinese driver work perfect
12V TTL 1W 1.6W 3W 445nm 450nm Laser Diode LD Driver Power Supply Stage Light | eBay
What I do wrong?
