Hi team,
The customer don't understand the set value of the output voltage.
In my understanding, they should set Vo = VF x n(LED#). Is it correct?
Or add voltage for condition fault monitoring?

Hi MIYAOKA,
our expert is in the sick leave and he will provide suggestion once back to the office.

Hi MIYAOKA,
please refer to the below equation for VLED calculation:
VLED = VF * N(LED NUMBER) + Current Sink Headroom(0.7V) + Vdrop
VF: LED forward voltage
Current Sink Headroom: 0.7V
Vdrop: the VLED voltage drop caused by PCB layout resistance. you can remain some margin when design the VLED voltage.

HI, Youhei
For a quick calculation of the output voltage, (Vf * n + 5V) is a quick calculation equation.
