.. LM5072 Integrated 100V Power Over Ethernet PD Interface and PWM Controller with Aux Support March 2006 LM5072 Integrated 100V Power Over Ethernet PD Interface and PWM Controller with Aux Support General Description The LM5072 Powered Device (PD) interface and PulseWidth-Modulation (PWM) controller provides a plete power solution, fully pliant to IEEE 802.3af, for the PD connecting into Power over Ethernet (PoE) networks. This controller integrates all functions necessary to implement both a PD powered interface and DC-DC converter with a minimum number of external ponents. The LM5072 provides the flexibility for the PD to also accept power from auxiliary...
