LTC4267IDHC-3#TRPBF

Overview

The LTC4267IDHC-3#TRPBF is a Power Over Ethernet (PoE) Powered Device (PD) controller designed for IEEE 802.3af compliant applications. It integrates a high-efficiency 300kHz current-mode switching regulator to provide a complete power solution. The device accepts an input voltage range of 10V to 57V and delivers a regulated output, such as 12V at up to 900mA. Packaged in a compact 16-pin DFN with an exposed pad measuring 5mm x 3mm x 0.7mm, it supports surface-mount installation.

Feature Summary

Integrates an IEEE 802.3af PD interface with a 300kHz current-mode switching regulator
Provides a complete power solution for Powered Device applications
Supports wide input voltage ranges typical of PoE standards

Applications

IEEE 802.3af Powered Device interfaces
Power management for networked devices
Evaluation using DC1145B demonstration boards

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the component is available from authorized Analog Devices distributors or verified electronic component suppliers. Ensure the supplier provides valid documentation matching the manufacturer's specifications for this part number.

Selection Notes

Select this component for designs requiring integrated PoE classification and regulation in a small footprint. It is suitable for applications needing a single-chip solution for IEEE 802.3af compliance. Consider the 16-pin DFN package constraints and thermal requirements associated with the exposed pad design.

Part Context

This part belongs to the LTC4267 series of PoE controllers manufactured by Analog Devices. It is functionally related to other variants like the LTC4267CDHC-3 and evaluation tools such as the DC1145B and DC804B-A. The series targets efficient power delivery for network infrastructure and endpoint devices.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing circuit designs before considering alternative components.
