LM5072MH-80

Overview

The LM5072MH-80/NOPB is a Power Over Ethernet (PoE) Powered Device controller compliant with IEEE 802.3af standards. It integrates a DC/DC converter and PD interface within a single 16-HTSSOP package. The device operates on a supply voltage range of 9V to 70V, supporting a maximum power output of 12.95W. It features an internal current consumption of 2mA maximum and functions reliably across a temperature range of -40°C to 125°C.

Feature Summary

• Integrates PoE PD interface and PWM controller for simplified design
• Supports auxiliary power functionality alongside main data channels
• Includes internal switching elements for efficient power conversion

Applications

• IEEE 802.3af compliant network endpoint devices
• VoIP telephones and wireless access points
• Security cameras and surveillance systems
• Industrial IoT sensors requiring remote power

Procurement Notes

Verify the complete ordering part number includes the /NOPB suffix to ensure compliance with RoHS 3 specifications and lead-free manufacturing processes. Confirm that the specific tape and reel packaging variant matches the required production volume and handling equipment capabilities before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring integrated PoE reception and power management in a compact surface-mount footprint. Ensure the application input voltage remains within the specified 9V to 70V operational window. Consider the thermal performance requirements given the 125°C maximum junction temperature rating for high-density layouts.
