Recently built a laser with the X-Boost 150mA-1.8A. I love it so far!
:thinking: I think I killed my rectangular X-boost. I hooked it up the the test load And it measured 1.26v (1.2a) the pot adjusted it a bit but not much. I soldered the "range 2 bridge" resistors and set it back up on the test load and it flickered and dropped to 0.00
I never heat sink mine when setting them up, but they are never on for more than a few seconds.
I power it up, check my reading, power it down, adjust, power it up and check, power it down, repeat as needed.
I mainly do it that way so my test load doesn't heat up and give me inaccurate readings. Maybe doing it that way saves the drive too ?
I simply don't know. That way works for me though.
I don't know how that could be. The X-Boost will smoke in a fraction of a second with no
heatsink at 1.8A. At 1A it still smokes after several seconds.
