Other Parts Discussed in Thread: LM3481,
We have two circuits, which from what we can tell are identical. It boosts 18V to 24V. One circuit is working, one is not (only boosts about 1V).
However, when looking at the markings on the components, the one that is working has the marking "8215 SUAB" and the one that is not has the marking "82FF SUAB".
What does the 15 vs FF marking mean?
