Part Number: LM5005
Other Parts Discussed in Thread: TPS54325

Hi Team,

Layout example shows the following.
Is it possible to fill the following clearance between FB trace and OUT trace (red part) if my customer designs layout?

I cannot comment directly on LM5005, but we have a part TPS54325 with a similar requirement. Obviously it is electrically equivalent to have a single conductor trace from the output voltage point of regulation to the OUT pin and the FB resistor divider network. We recommend using separate traces for better regulation performance.
