Part Number: LM5146-Q1 Hello,
On page 31, in Table 9-2 of the datasheet of LM5146-Q1, the power stage zero formula is mentioned as below (in red circle) -
I think the formula is wrong, it should be wL = Rdamp / LF, because this can make inductive…

Hello Kotaro
Kotaro Suzuki said: C15 is placed close to the IC, but is wired with a thin wire on the inner layer.
Device won't carry much current; it will in few mA. Thus, you don't need thicker trace. Following circuit comes in input power…
