LM5070 Integrated Power Over Ethernet PD Interface and PWM Controller

FEATURES  
DESCRIPTION  
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.
