Hi
I am having difficulty in routing high voltage to low voltage buck converters on embedded automotive boards (specifically 24V to 5V --3A converters) I am using a 6 layer stackup with TOP--> GROUND PLANE--> SIGNAL1 --->SIGNAL 2 --->POWER PLANE----> BOTTOM. most of these buck converters have reference layout for (2 Layer or 4 layer ) and many times these converters end up failing due to ground loops,These converters work very good if i use them as a standalone PCB and connect to my embedded board via connectors. I need to use the converter on the same board and require some help on what is to be taken care when routing specially ground since it is a non isolated buck converter it shares a common ground.
