LTC9102AUKJ#PBF

Overview

The LTC9102AUKJ#PBF is a Power Switch IC designed for IEEE 802.3bt PoE Powered Devices (PD). It supports high-power applications up to 71W output power. The device operates with a supply voltage range of 4V to 60V and features an integrated forward/flyback controller. It includes comprehensive protection mechanisms such as over-current, over-voltage, and thermal shutdown. The component is housed in a QFN-28 package suitable for surface mount assembly.

Feature Summary

• Integrated forward/flyback controller for efficient power conversion
• Supports IEEE 802.3af/at/bt standards for flexible PoE deployment
• Comprehensive protection against over-current, over-voltage, and thermal events

Applications

• High-power IoT devices requiring up to 71W
• Wireless access points and base stations
• Medical ultrasound equipment
• Industrial automation controllers

Procurement Notes

Verify the specific suffix UKJ corresponds to the QFN-28 package variant when sourcing. Confirm RoHS compliance status through official Analog Devices documentation prior to integration. Ensure the procurement channel provides valid traceability data for quality assurance purposes.

Selection Notes

Select this component for designs requiring integrated PoE PD control and power conversion. Consider the QFN-28 footprint for space-constrained layouts. Evaluate thermal management requirements given the 71W output capability. Verify compatibility with existing flyback transformer designs.
