Frequently asked questions
Can I use this chip alone to power a board from Ethernet?
No. It is a PoE interface and controller IC, so the design also needs external parts such as a transformer, power switch and output stage. Follow the datasheet reference design.
Which PoE standard does it support?
The listing states IEEE 802.3at Type 1 as a 13 W powered device. Check the datasheet for the full classification and detection behavior before designing a PoE supply.
