Has anyone received and put one of these together yet? Looking to use an osram flat black just wondering if anybody has done this combo with one of these boards yet
So does anyone know if this is this an inverted copy of a blf a6 driver? Can I just remove all components from the a6 driver and put them on this board?
Now I am confused too, and I think we all made a mistake :person_facepalming:
The OP states that Oslon Black leds have the anode (led+) connected to the thermal pad, in which case this reversed driver would work, but unfortunately that is not true: the cathode (led-) is connected to the thermal pad instead. So a reversed driver will not work.
I’m not really into IR leds but as part of a Mouser order in a wave I bought a new Luxeon IR led (https://www.lumileds.com/infrared-emitters/luxeon-ir-domed-line), partnr. L1I0-0850090000000 , do you know they are any good compared to the Oslon IR leds?
(for oslon black flat : ) So… A suitable driver would be good if it used a pfet instead of nfet that we use now . Basically to regulate the positive instead of the negative .
I did have the IR LEDs checked in datasheet and physically here, did not check black flats to be different, no idea why they are not doing it at least on all the same
At least with normal driver and the black flats worst thing happen is DD if star insulation fails
It should be possible to insulate the star with a thin insulator sheet of aluminum oxide
