Worst Case Current Consumption

This section details the worst case current consumption for each device power supply. These values

are provided to assist system designers with proper power supply design. These values cannot be

used to determine typical power consumption of the device.

Note: The current measurements listed below were taken under the following conditions:

Temperature: ........................................................................................................................0oC to +70oC

Device VDD:.................................................................................................................. +3.30 V +/- 10%

Note: Current consumption is determined by operating frequency, temperature, and supply voltage,

as well as external source/sink requirements.

Note: Above values do not include the supply current for the magnetics. Based on the recommended

implementation, the maximum supply current needed for the magnetics is 108mA.
