Hi maybe i don’t under stand fully how it works.
But let me try to explain.
I’m connecting a 5v arduino to ltc 1871 5v to 12v step up.
When I don’t connect to the output. The led lights up and says its 4.9.
But as soon as I connect to the output an electromagnet that requires 12v.
It seems to stop working until I remove the load from the output.
