Product Overview

The LM5070MTC-50 is a 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 a 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.
  • Fully compliant 802.3af Power interface port
  • 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 reference for non-isolated applications
  • Programmable oscillator frequency
  • Programmable soft-start
  • 800mA Peak gate driver
  • Green product and no Sb/Br
