I am using a 4 layer board.
L1: SIGNAL
L2: PWR
L3: GND
L4: SIGNAL
I have a DC to DC Converter on L4 and inductor concerned on L1.
On power plane I am removing the complete etch under the converter.
Should I also remove the GND or stitch the same with vias??
And what if I stitch too and wouldnt that be a return path for DC to DC and that noise has effect on other grounds
If I have a separate power ground plane beneath DC to DC and connect that ground to other digital gnd plane via one or two point connection. Is that a good option
