Overview
The LT4275AIMS#TRPBF is a single-channel Powered Device (PD) controller from Analog Devices Inc., designed for Power over Ethernet applications. It supports IEEE 802.3af, 802.3at, and the proprietary LTPoE++ standards. The device operates with an input voltage range of 9V to 60V and delivers up to 90W of output power. It features a 10-WFDFN package with a 3x3mm footprint and is rated for an operating temperature range of -40°C to 85°C. The supply current is typically 2mA maximum.
Feature Summary
- Supports IEEE 802.3af/at and LTPoE++ classification schemes
- Integrated high-efficiency DC-DC conversion capability
- Pin-for-pin compatible across the LT4275 family
Applications
- IEEE 802.3af PoE powered devices
- IEEE 802.3at PoE+ powered devices
- LTPoE++ high-power powered devices
Procurement Notes
Verify the specific suffix 'IMS' corresponds to the 10-WFDFN package and tape-and-reel packaging format. Confirm that the 'A' variant designation aligns with the required LTPoE++ classification support and power delivery specifications for your design. Ensure the component meets RoHS compliance requirements as indicated in the manufacturer documentation.
Selection Notes
Select this component when designing systems requiring compatibility with both standard IEEE PoE protocols and extended power LTPoE++. The choice depends on the need for a single-channel solution supporting up to 90W power delivery within a compact surface-mount footprint. Consider the thermal performance requirements associated with the DFN package for high-power operation scenarios.
Part Context
This part belongs to the LT4275 family of PD controllers, which are pin-for-pin compatible. The LT4275 series provides a scalable solution for various PoE standards, allowing designers to upgrade power capabilities without changing the PCB layout. The 'A' suffix indicates specific feature sets related to advanced classification and power management compared to other variants in the family.
