The LM5073 Power Delivery Equipment (PD) interface provides a high-performance solution for powering PD connections to Power over Ethernet (PoE) networks, which is fully compliant with the IEEE 802.3af standard. The LM5073 offers the flexibility to also accept power from unregulated secondary sources such as AC adapters and various configurations of solar cells for PD. Low R_DS(ON).The PD interface hot-swappable MOSFETs and programmable DC current limit LM5073 extend the application range to double the power level of IEEE 802.3af-compliant devices. Up to 100V, simplified transient voltage suppressor with rated voltage, PD selection from network transient protection. Provides a control output for a stand-alone DC-DC converter, allowing freedom to select the optimal DC-DC converter for a particular application topology.
