Procurement Notes

Verify the specific suffix 'ETE+' against the official Analog Devices datasheet to confirm package type and temperature range. Ensure compatibility with your system's voltage requirements and thermal management design. Confirm RoHS compliance status as per the latest manufacturer documentation before finalizing procurement.

Selection Notes

Select this component for designs requiring full IEEE 802.3bt support with integrated power conversion. Evaluate thermal performance based on the maximum power dissipation of 91W. Consider the 16-TQFN package constraints for PCB layout and heat sinking requirements during the initial design phase.

Part Context

This part belongs to the Maxim Integrated PoE controller family, now under Analog Devices. It addresses the need for compact, high-power density solutions in modern networking infrastructure. The integration of DC/DC and switching functions reduces external component count compared to discrete solutions.
