KTA1136EUAE-TR

Overview

The KTA1136EUAE-TR is a Powered Device (PD) power switch IC compliant with IEEE 802.3af PoE standards, manufactured by Kinetic Technologies. It integrates a DC-DC controller and a 13W power FET within a single TQFN-16 package. The device operates on a supply voltage range of 37 V to 57 V and features a current limit of 640 mA. It supports a maximum duty cycle of 85% and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

Integrates a dedicated DC-DC controller with a high-efficiency power FET for compact PoE PD designs.
Complies with IEEE 802.3af Power over Ethernet standards for powered device classification.
Provides internal current limiting protection to safeguard the load and the integrated switch.

Applications

IEEE 802.3af compliant Powered Devices
PoE-powered network endpoints
Integrated LAN power management circuits

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm that the TQFN-16 package dimensions align with your PCB footprint requirements. Ensure the design accommodates the specified thermal dissipation characteristics for the intended ambient temperature range. Cross-reference the manufacturer part number directly to avoid confusion with similar family members.

Selection Notes

Select this component for applications requiring a single-chip solution for 802.3af PoE PDs. It is suitable where space constraints favor the TQFN-16 package over larger alternatives. Consider the 640 mA current limit and 13W power capability against the target load requirements. Verify compatibility with the 37 V to 57 V input voltage window provided by the PoE source.

Part Context

This part belongs to the Kinetic Technologies power switch IC family designed for LAN and PoE applications. It serves as a complete power management block for powered devices, combining switching regulation and power delivery in one integrated circuit. The series focuses on simplifying board layout and reducing component count for standard PoE implementations.
