USB 2.0 Hub and 10/100 Ethernet Controller

Datasheet

SMSC LAN9512/LAN9512i

Revision 1.0 (11-24-09)

DATASHEET

4.3

Power Consumption

This section details the power consumption of the device as measured during various modes of

operation. Power dissipation is determined by temperature, supply voltage, and external source/sink

requirements.

4.3.1

Operational Current Consumption & Power Dissipation

Note: All values measured with maximum simultaneous traffic on the Ethernet port and all USB ports.

Note: Magnetic power consumption:

100BASE-TX: ~42mA

10BASE-T: ~104mA
