LTC4263CS#PBF

Overview

The LTC4263CS#PBF is a single-channel Power Sourcing Equipment (PSE) controller compliant with IEEE 802.3af standards for Power over Ethernet systems. It integrates an on-board power MOSFET, internal inrush current control, and short-circuit protection. The device operates within a supply voltage range of 33 V to 66 V and features a maximum current limit of 425 mA. It utilizes a 14-lead SOIC surface-mount package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

Autonomous operation for IEEE 802.3af compliant PoE applications
Integrated on-board power MOSFET for compact design
Built-in inrush current limiting and short-circuit protection

Applications

IEEE 802.3af Power over Ethernet controllers
Single-channel PSE implementations
LAN infrastructure power distribution

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when reviewing distributor listings. Confirm the manufacturer part number matches exactly to ensure correct RoHS compliance status. Check for any regional shipping restrictions or limited availability notices provided by authorized suppliers before finalizing procurement plans.

Selection Notes

Select this component for designs requiring a single-channel autonomous PSE solution. Ensure the system voltage remains within the 33 V to 66 V operational window. Verify that the 14-lead SOIC footprint aligns with the PCB layout constraints. Consider the 425 mA current limit when sizing downstream loads.

Part Context

This part belongs to the LTC4263 series of PoE controllers from Analog Devices. It serves as a complete solution for powering remote devices over Ethernet cabling. The series includes variants with different packaging options such as tape-and-reel configurations for automated assembly processes.

Replacement Considerations

LTC4263CDE-1#PBF offers similar functionality but uses a DFN-14 package instead of SOIC. LTC4263IDE#TRPBF provides the same electrical characteristics in a reel format. Verify pin compatibility and thermal performance when substituting these alternatives.
