Title: Connection pin layout for connecting integrated magnetics modules to a printed circuit board

Abstract: A connection pin layout for connecting one or more integrated magnetics modules (IMMs) to a printed circuit board (PCB) for reduced electromagnetic interference (EMI) includes grouping and locating the connection pins based on the signals passed through the connection pins and a method of routing traces to the connection pins. The connection pins carrying power between the PCB and the IMMs are located together and on the periphery of the connection pin layout. The traces to the power pins are routed to avoid passing under the data and ground connection pins or crossing the traces to the data and ground connection pins. When multiple IMMS are connected to a PCB, the connection pin layout coordinates the location of connection pins among IMMs and integrates the grouping of the connection pins for multiple IMMs.
