The most critical node in the schematic is the SW pin. In the physical layout, the trace connecting the SW pin to the inductor acts as an antenna. If this trace is too long, it radiates EMI, creating noise that can couple back into the sensitive FB pin. Therefore, the schematic implies a layout strategy where the inductor is placed immediately adjacent to the SW pin. Key sections of the internal layout include: Input
