DP83869HM: Current Draw for Each Power Supply

Mike Hubert23

Part Number: DP83869HM
Other Parts Discussed in Thread: DP83869

I am working on designing the DP83869 into our new product. I will be using it to convert from RGMII to SGMII for Gigabit operation. I will be using external power supplies for all of the power and 1.8V for VDDIO. What is the current draw from each of the different power supplies in the chip? I saw the overall chip power spec (W) in the datasheet but couldn't find the current (I) for each supply. Knowing this information will help in choosing appropriate power supply chips for each of the supplies. Thanks.

Hi Mike

Here is an E2E thread of the current draw for the different rails of the DP83869

Thanks

Thanks Cecilia. I couldn't find that thread when I did a search.

I'm also likely to be using the chip in RGMII to SGMII bridge mode. Will the current draw for bridge mode be the same as the RGMII to 1000Base-X specification from the thread you quoted? Thanks.

Hi Mike

It should be about the same approximately.

Thanks!
