    [Resolved]Blackbuck 8a v2 issues

    Re: Blackbuck 8a v2 issues Anyway so that you know - if the copper layers on the pcb are not damaged, this driver can be repaired.

    [Resolved]Blackbuck 8a v2 issues

    Re: Blackbuck 8a v2 issues You are right about the pot, but anything could happen. All drivers was tested and preconfigured to 1.6A by me personally, this excludes the fact that you could get 3 DOA drivers. Something is wrong with the connections or soldering. The only way to kill this driver...

    [Resolved]Blackbuck 8a v2 issues

    Re: Blackbuck 8a v2 issues Hi guys. DTR contacted me a couple of hours ago. Most likely it's my fault, I did not take care of properly updating the manual for V2. If you had smoke, it's likely that 5V reference chip is dead. To find it out - check the voltage between the ref and gnd pins. Now...

    Blackbuck 3 fail

    These laser diodes has approx 0.8nm/10°C wavelength thermal shift. Thus, in order to rise it to 470nm you should add at least 40 degrees to the rated temperature. Normally the rated chip temperature is much higher than the diode case temperature (depending on operating current and heatsinking)...

    Blackbuck 3 fail

    I always read the datasheet before posting - this is the first thing that I should pay attention to. Also I have an experience with some NDB7875s, which died at double overcurrent. In your opinion, if the diode remained alive after 3A kick - this is your luck, if it died - the driver issue...

    Blackbuck 3 fail

    Hello LPF, I'm sorry that my first post here, not in welcome section, but the issue requires my comment )) NDB7675 has 1.4A operating current ratings and 1.7A absolute maximum ratings... You have applied 3A and are surprised the diode has down into LED brick. All that you are applying above...
