產品總覽
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
