    November 2005 www.DataSheet4U.com LM5071 Power Over Ethernet PD Controller with Auxiliary Power Interface LM5071 Power Over Ethernet PD Controller with Auxiliary Power Interface General Description The LM5071 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 LM5071 is specifically designed for the PD that must accept power from auxiliary sources such as ac adapters. The auxiliary power interface of the LM5071 activates the PWM controller when the ac adapter is connected to power the PD when PoE network power is unavailable. The LM5071 integrates an 80V, 400mA line connection switch and associated control for a fully IEEE 802.
