PoE Powered Device (PD)
Analog Devices powered device (PD) controllers support multiple power levels of power over Ethernet: IEEE PoE (13W), IEEE PoE+ (25.5 W), IEEE PoE++ (71 W), and ADI LTPoE++ (up to 90 W) standard. PD controllers are ultimately responsible for providing the correct signature and classification to power sourcing equipment (PSE), so that PSEs source the right amount of power to PDs over the Ethernet cables. Some of our PD controllers integrate efficient dc-to-dc converters to simplify designs, while our other PD controllers give designers the ability to choose their own dc-to-dc converters, which helps designers achieve unique cost-efficiency requirements.
