LTC4269CDKD-2#TRPBF

Overview

The LTC4269CDKD-2#TRPBF is a Powered Device (PD) controller compliant with IEEE 802.3at standards for high-power Power over Ethernet applications. It integrates a hot-swap controller, power switch, and classification logic within a DFN-32 package. The device supports Class 4 power delivery up to 30W, enabling robust power management for LAN-connected equipment requiring elevated power levels while maintaining strict protocol adherence.

Feature Summary

• Integrates IEEE 802.3at classification logic for accurate power negotiation
• Combines hot-swap control with integrated power switch functionality
• Supports high-power PD applications up to 30W output capability

Applications

• High-power PoE powered devices
• IEEE 802.3at compliant network endpoints
• LAN-powered industrial equipment

Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to limited supply status. Confirm the specific suffix matches the required tape-and-reel packaging configuration. Ensure compatibility with existing IEEE 802.3at infrastructure before integration into final designs.

Selection Notes

Select this component when designing systems requiring full IEEE 802.3at compliance with integrated power switching. The DFN-32 package offers thermal efficiency for high-current applications. Consider availability constraints given the restricted supply status mentioned in distributor records.

Part Context

This part belongs to the LTC4269 series of PoE controllers designed for Powered Devices. It represents a specialized solution for managing power delivery in network environments where higher power budgets are necessary compared to standard PoE implementations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other IEEE 802.3at PD controllers if direct replacement is required.
