LM5070SDX-50/NOPB

Overview

The LM5070SDX-50/NOPB is a single-channel Power over Ethernet (PoE) controller compliant with the IEEE 802.3af standard, designed for Powered Device (PD) applications. It integrates a current-mode DC/DC controller and operates within a supply voltage range of 1.8V to 75V. The device utilizes a 16-WSON package measuring 5x5 mm and supports surface-mount installation. It functions as both a PD controller and a DC/DC converter, featuring user-programmable under-voltage thresholds and hysteresis alongside a fault current control loop.

Feature Summary

Integrates a current-mode DC/DC controller with a dedicated PoE interface
Provides user-programmable under-voltage threshold and hysteresis settings
Includes a fault current control loop for enhanced protection

Applications

IEEE 802.3af compliant Powered Device implementations
Single-channel PoE power management systems
DC/DC conversion stages in networked devices

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm exact packaging and tape/reel specifications. Ensure the component matches the required 802.3af compliance level for your design. Cross-reference the 16-WSON package dimensions with your PCB footprint library. Confirm operating temperature ranges align with your environmental requirements before finalizing procurement.

Selection Notes

Select this component for designs requiring integrated PoE detection and DC/DC regulation in a compact form factor. The 1.8V to 75V input range accommodates various PoE power sourcing equipment voltages. Consider the 16-WSON package size constraints during layout. Verify that the internal switch configuration meets the load requirements without external components.

Part Context

This part belongs to the LM5070 family of PoE controllers from Texas Instruments. It serves as a solution for integrating power delivery and conversion in a single chip. The SDX variant indicates a specific reel-based packaging option within the broader LM5070 product line, maintaining core functional compatibility with other suffixes while differing in logistics.
