I have an issue, i want to power my pi and 7" touchscreen over poe but the raspberry pi poe hat supplies only 2.5 amp. 

7" touchscreen requires 2.5 amp and rpi 3 b+ also requires 2.5 amp so i am in need of a poe hat that supplies 5 amp.

So far i did not even find a poe module that can supply 5v 25w the closest on from silvertel gives 5w 13w or 12v 30-ish w. 

Is there any module that can do that or i am stuck with 12v 30w module plus a dc/dc module 12v to 5v?

Many thanks!
