The LM5070 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 LM5070 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. Two options are available providing either an 80% maximum duty
cycle limit with slope compensation on the (-80 suffix) device or a 50% maximum
duty cycle limit and no slope compensation on the (-50 suffix) device.
