LTC4269IDKD-1#PBF

Overview

The LTC4269IDKD-1#PBF is a Powered Device (PD) controller compliant with IEEE 802.3at standards, designed for high-power Power over Ethernet applications. It operates within a 60 V supply voltage range and supports up to 25.5 W output power. The device features a 100 mA current limit and draws 6.4 mA of operating supply current. It functions reliably across an industrial temperature range from -40°C to +85°C. Packaged in a 32-pin DFN EP format, it integrates control logic for PoE systems.

Feature Summary

Supports no-opto flyback converter topologies for efficient power conversion
Complies with IEEE 802.3at high-power Powered Device standards
Integrates precise current limiting and thermal protection mechanisms

Applications

High-power Powered Device implementations
No-opto flyback converter designs
IEEE 802.3at compliant network equipment

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the ID variant meets the required -40°C to +85°C industrial temperature range specifications. Ensure the 32-pin DFN package footprint matches the target PCB layout constraints before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring strict adherence to IEEE 802.3at protocols with integrated flyback control capabilities. The industrial grade rating suits environments with significant thermal variations. Consider the 32-pin DFN package size relative to available board space and thermal dissipation requirements for optimal system integration.

Part Context

This part belongs to the LTC4269-1 series of PoE controllers manufactured by Analog Devices. It serves as a specialized solution for managing power delivery in network infrastructure. The device distinguishes itself by combining PD classification with synchronous rectification control, simplifying the design of high-efficiency power stages.
