Integrated Power Over Ethernet PD Interface and PWM
Controller
General DescriptionThe LM5070 power interface port and pulse width modula-
tion (PWM) controller providesa complete integrated solu-
tionfor Powered Devices (PD) that connect into Power over
Ethernet (PoE) systems. The LM5070 integratesan 80V,
400mA line connection switch and associated controlfora
fully IEEE 802.3af compliant interface witha full featured
current mode pulse width modulator dc-dc converter.All
power sequencing requirements between the controllerin-
terface and switch mode power supply (SMPS) are inte-
grated intotheIC. Two options are available providing either 80% maximum duty cycle limit with slope compensation
(onthe –80 suffix) deviceora 50% maximum duty cycle limit
andno slope compensationonthe (–50 suffix) device.
Features Fully Compliant 802.3af Power Interface Port 80V, 1Ω, 400 mA Internal MOSFET Programmable Inrush Current Limit Detection Resistor Disconnect Function Programmable Classification Current Programmable Under-voltage Lockout with
Programmable Hysteresis Thermal Shutdown Protection Current Mode Pulse Width Modulator Supports both Isolated and Non-Isolated Applications Error Amplifier and Referencefor Non-Isolated
