Power Consumption (Device and System Components)
This section provides typical power consumption values for a complete Ethernet interface based on
the LAN9215i, including the power dissipated by the magnetics and other passive components. All of
these values are preliminary.
Please refer to the SMSC application note AN14.9 - “Migrating from LAN9115 to the LAN9215”, that
can be found on SMSC’s web site www.smsc.com, which contains additional details on magnetics and
other components used.
Note: The power measurements list below were taken under the following conditions:
Temperature: ................................................................................................................................... +25°C
Device VDD:................................................................................................................................... +3.30V
