LM5070MTC-50, POE контроллер, 48В/1.5мА, генератор 580кГц, 6.25В пороговое значение блокировки питания при ПН

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
