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 Microchip Ethernet controller. The values below should be used as comparison

measurements only for power provisioning.

Please refer to application note “AN 12-5 Designing with the LAN9118 - Getting Started”, that can be found on Micro-

chip’s web site www.microchip.com, which details the magnetics and other components used.

Power measurements taken under the following conditions:

Temperature: .......................................................................................................................................................... +25

 C

Device VDD: .........................................................................................................................................................+3.30 V

Note 7-6

Each LED indicator in use adds approximately 4 mA to the Digital power supply.
