power consumption to design for DP83867

Ken Hashi

Hello.

Customer designs the power supply to use for DP83867.

The typcal value of the current consumption is written on DP83867 data sheet P.9, but the max value is not written.
How much current capacity is necessary for 2.5V and 1.1V to design the board?

This design uses Dual Supply Voltage (2.5V and 1.1V).

Regards.

Hello K Hashi,

The maximum current consumption for dual supply configuration at room temperature is as follows;

2.5V Supply: approximately 160mA

1.1V Supply: approximately 110mA

A good design practice would be to add an additional margin of atleast 5-10mA when designing power supplies.

Hi, Aniruddha

Thank you for your reply.
I understood that even a maximum current value was such not different.

Best regards,
