符合IEEE 802.3af标准,高效率, 1级,具有集成DC -DC转换器供电设备 IEEE 802.3af-Compliant, High-Efficiency, Class 1,Powered Devices with Integrated DC-DC Converter
The from Products is an IEEE 802.3af-compliant, high-efficiency, Class 1/Class 2, PDs with integrated DC to DC converter in 16 pin TQFN package. It provides a complete power-supply solution as IEEE® 802.3af-compliant Class 1/Class 2 powered devices in a Power over Ethernet system. The device integrates the PD interface with an efficient DC to DC converter, offering a low external part count PD solution. The MAX5986A include sleep and ultra-low power modes. The PD interface provides a detection signature and a Class 1/Class 2 classification signature with a single external resistor. The PD interface also provides an isolation power MOSFET, a 60mA max inrush current limit and a 323mA operating current limit. The integrated step down DC-DC converter uses a peak current-mode control scheme and provides an easy-to implement architecture with a fast transient response. It operates at a fixed 215KHz switching frequency.
