Procurement Notes
Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix #TRPBF indicates tape-and-reel packaging. Check for RoHS compliance documentation and ensure the part matches the exact manufacturer number to avoid counterfeits. Request lot traceability data for critical industrial or commercial deployments.
Selection Notes
Select this component when designing systems requiring IEEE 802.3at compliance with integrated current limiting. It is suitable for applications needing wide input voltage tolerance and high-temperature stability. Consider the 12-lead DFN package constraints for PCB layout. Ensure the external components match the datasheet recommendations for stable operation under varying load conditions.
Part Context
This part belongs to the LTC4264 series of PoE PD interface controllers from Analog Devices. It is engineered for reliable power delivery in network infrastructure. The IDE suffix denotes an industrial temperature grade, ensuring performance in harsh environments compared to commercial variants.
Replacement Considerations
Consult official Analog Devices documentation for direct pin-compatible substitutes within the same family. Verify that any alternative maintains IEEE 802.3at compliance and equivalent current limiting specifications.
