LT4275CIMS#PBF

Overview

The LT4275CIMS#PBF is a Powered Device (PD) controller supporting IEEE 802.3af/at/bt and LTPoE++ standards. It operates with an input voltage range of 9V to 60V and supports output power up to 90W. The device features proprietary classification for high-power applications, including 38.7W, 52.7W, 70W, and 90W levels. It integrates DC-DC conversion topology capabilities and includes auxiliary input support for 12VDC and 24VAC sources.

Feature Summary

Supports IEEE 802.3af/at/bt and LTPoE++ powered device protocols
Enables high-power delivery via proprietary classification schemes
Integrates DC-DC conversion functionality within the PD interface
Provides compatibility with auxiliary power inputs

Applications

High-power PoE powered devices requiring LTPoE++ support
Industrial equipment utilizing auxiliary 12VDC or 24VAC inputs
Network infrastructure endpoints needing 90W power budgets

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm package integrity and pin alignment against the IMS specification. Ensure compliance with RoHS directives as indicated by the PBF suffix. Review current availability status due to potential supply constraints common in specialized PMIC components.

Selection Notes

Select this controller for designs requiring strict adherence to IEEE 802.3bt standards alongside legacy PoE compatibility. Consider the IMS package for thermal management needs in compact form factors. Evaluate auxiliary input requirements if hybrid power sourcing is necessary for system redundancy or startup conditions.

Part Context

Part of the LT4275 family of pin-for-pin compatible PD controllers from Analog Devices. Designed to replace older generation interfaces while offering enhanced power delivery capabilities. Shares architectural similarities with LT4276 but lacks integrated forward/flyback control, focusing instead on pure PD interface management.

Replacement Considerations

LT4275A variants offer different classification profiles. LT4276 provides integrated converter control. Verify pinout compatibility before substitution. Check specific electrical characteristics against original design requirements.
