Hey guys i am wondering what is the best way to see if i have broken an LED driver or if it came broken or working? I do not have a test power source but i could rig one up with batteries. I have a few FET driver i need to test and an LD29s i can not get to work for my XHP50. With the LD29s its a boost driver so a continuity test will not work to see what wire is positive and what wire negative?
I think i may have shorted one of the FET driver so the fet its self is probably broken can i double check that?
if you just want to test the driver you could do that with a DMM (testing against shorts, output pins, with power source you could also check on modes, you could change the firmware/flash the driver, …)
More luxurious would be a test station with a heat sink, mcpcb (test led), a power source …
or if most of your drivers are the same size you could use an old host for them - but that would require assembly.
set DMM to continuity mode and check pill against Bat+ would be one example. If your multimeter doesn’t have a dedicated continuity test mode, you can still do this, set it to the lowest setting in the resistance test and see what comes up. You can measure your capacitors, resistors, see whether all pins are right, (…)
I always check drivers after assembly, after adding leads, and then after putting it into the pill.
If you work on lights/build your own lights always check for shorts before putting the battery in!
