ADD5205 specification Fig9

Hi

We would like to know the horizontal axis of Figure-9.

20mSec/div?

Fig-10 to 13 were also missing those data.

Regards

moto

    Hi Moto,

    Sorry about that.  I'll try to find the original oscope picts.  If not, I can retake that image.  Is it the time from EN to LED current that you are wondering about?  The ADD5205 does have a longer EN delay time than our other LED drivers.  This is because the PWM to DC current filter needs to gather enough PWM cycles to produce a constant filter output. 

    Best Regards,
