Power Consumption Device and System Components
This section describes typical power consumption values of a total Ethernet LAN connectivity solution,
which includes external components supporting the SMSC Ethernet controller. The values below
should be used as comparision measurements only for power provisioning.
Please refer to application note “AN 12-5 Designing with the LAN9118 - Getting Started”, that can be
found on SMSC’s web site www.smsc.com, which details the magnetics and other components used.
