LTC4267CGN-3#TRPBF

Overview

The LTC4267CGN-3#TRPBF is a Power Over Ethernet (PoE) Powered Device (PD) controller compliant with IEEE 802.3af standards, manufactured by Analog Devices Inc. It integrates a 300kHz current-mode switching regulator to provide a complete power solution for PD applications. The device operates within an input voltage range of 44V to 57V and features an adjustable current limit. Packaged in a 16-lead DFN EP (5mm x 3mm), it supports surface-mount installation and functions across a temperature range of -40°C to +85°C.

Feature Summary

Integrates an IEEE 802.3af compliant PD interface with a high-efficiency 300kHz switching regulator
Provides a compact, complete power solution for Powered Device applications
Features internal current mode control for stable regulation

Applications

IEEE 802.3af Powered Device (PD) interfaces
Network equipment requiring integrated PoE power management
Compact electronic systems utilizing Power over Ethernet

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the CGN variant meets commercial temperature specifications (-40°C to +85°C). Ensure compatibility with IEEE 802.3af standards for the intended Powered Device application before finalizing procurement.

Selection Notes

Select this component for designs requiring a combined PoE interface and DC-DC conversion in a small footprint. The integrated 300kHz regulator reduces external component count compared to discrete solutions. Consider the DFN package size constraints and thermal requirements for the specific PCB layout.

Part Context

This part belongs to the LTC4267 series of PoE controllers from Analog Devices. It is designed specifically for Powered Devices rather than Power Sourcing Equipment. The integration of the switch regulator distinguishes it from basic PD interface controllers, offering a more consolidated power architecture.
