LM5070 Overview
The LM5070 power interface port and pulse width modulation (PWM) controller provides a plete integrated solution for Powered Devices (PD) that connect into Power over Ethernet (PoE) systems. The LM5070 integrates an 80V, 400mA line connection switch and associated control for a fully IEEE 802.3af pliant interface with a full featured current mode pulse width modulator dc-dc converter. All power sequencing...
