The DC2093A board demonstrates a high efficiency PD solution by using the LT4321 in combination with the LT4275, which is a LTPoE++/PoE+/PoE PD controller. Both the top and bottom views of the board are shown here, with an Ethernet cable plugged into it. This board shows the compact layout that can be achieved by using an ideal diode bridge as PCB area does not need to be wasted for heat sinking. The next slide will show this board being loaded with 90W and looked at under a thermal camera.
