Other Parts Discussed in Thread: LM5155-Q1, LM51551
I was working with the LM5155-Q1 boost and have a question.
Our circuit is as in the typical application of the datasheet. I have cut the trace to the BIAS pin, so there’s no power going into the boost. But I see a 1.25V on the BIAS line. All the other lines are at 0V except BIAS line a 1.25V and PGOOD which is at 1.75V.
Is there something I am missing? Can you help me understand what is going on at the BIAS line.
