Got a TP-Link TL-POE10R Power-over-Ethernet (PoE) splitter (Ver: 4.0), complying with IEEE 802.4af; output is selectable: 5V/9V/12V into a 5.5mm OD, 2.1mm ID center positive barrel receptacle. Ethernet supports up to 1000Mbps.
It is not galvanically isolated and has a ground loop issue.
There is a Feeling Technology FP5001
PWM (pulse width modulation) controller with SCP (short-circuit protection) / DTC (duty control); click to enlarge.
There is a Linear LTC4257
PoE interface controller; click to enlarge.
