Product Summary

The LM5071MT-80/NOPB is a Power Over Ethernet PD Controller. The LM5071MT-80/NOPB power interface port and pulse width modulation (PWM) controller provides a complete integrated solution for Powered Devices (PD) that connect into Power over Ethernet (PoE) systems. The LM5071MT-80/NOPB is specifically designed for the PD that must accept power from auxiliary sources such as AC adapters. The auxiliary power interface of the LM5071MT-80/NOPB activates the PWM controller when the ac adapter is connected to power the PD when PoE network power is unavailable. The LM5071MT-80/NOPB integrates an 80V, 400mA line connection switch and associated control for a fully IEEE 802.3af compliant interface with a full featured current mode pulse width modulator dc-dc converter. All power sequencing requirements between the controller interface and switch mode power supply (SMPS) are integrated into the IC.
