The LM5071 power interface port and pulse width modulation(PWM) controller provides a complete integrated solutionfor Powered Devices (PD) that connect into Power overEthernet (PoE) systems. The LM5071 is specifically designedfor the PD that must accept power from auxiliarysources such as ac adapters. The auxiliary power interfaceof the LM5071 activates the PWM controller when theac adapter is connected to power the PD when PoE networkpower is unavailable. The LM5071 integrates an 80V,400mA line connection switch and associated control for afully IEEE 802.3af compliant interface with a full featuredcurrent mode pulse width modulator dc-dc converter. Allpower sequencing requirements between the controller interfaceand switch mode power supply (SMPS) are integratedinto the IC.
