Table 23. Power Consumption (82566DC/DM)
a. Solution power is the total amount of power from the 3.3V supply required for the 82566 to operate. In its mathematical form:
The current from the 82566 does not change regardless of generating the 1.0V using the on-die
transistor or an external pass transistor. The total current demand remains constant, but the power
dissipated by the 82566 package changes. The 1.0V power is either on-die or at the external pass
transistor.

solution power = (82566 current) * 3.3V. The 3.3V is assumed since this is the normal voltage rail provided to the LAN solution.
