LM5070  
Integrated Power Over Ethernet PD Interface and PWM  
Controller  
n Programmable Classification Current  
General Description  
n Programmable Under-voltage Lockout with  
The LM5070 power interface port and pulse width modula-  
Programmable Hysteresis  
tion (PWM) controller provides a complete integrated solu-  
tion for Powered Devices (PD) that connect into Power over  
Ethernet (PoE) systems. The LM5070 integrates an 80V,  
n Thermal Shutdown Protection  
n Current Mode Pulse Width Modulator  
n Supports both Isolated and Non-Isolated Applications  
n Error Amplifier and Reference for Non-Isolated  
Applications  
n Programmable Oscillator Frequency  
n Programmable Soft-start  
n 80% Maximum Duty Cycle Limiter, Slope Compensation  
(-80 device)  
n 50% Maximum Duty Cycle Limiter, No Slope  
Compensation (-50 device)  
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 in-  
terface and switch mode power supply (SMPS) are inte-  
grated 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.  
n 800 mA Peak Gate Driver  
Features  
n Fully Compliant 802.3af Power Interface Port  
n 80V, 1, 400 mA Internal MOSFET  
n Programmable Inrush Current Limit  
n Detection Resistor Disconnect Function  
Packages  
n TSSOP-16  
n LLP-16 (5 mm x 5 mm)
