Power Consumption
This section details the power consumption of LAN9420/LAN9420i as measured during various modes
of operation. Power consumption values are provided for both the device-only, and for the device plus
Ethernet components.
Note: Power dissipation is determined by operating frequency, temperature, and supply voltage, as
D0 - Normal Operation with Ethernet Traffic
well as external source/sink requirements.
