KIT34670EGEVBE评估板突出的评估了MC34670的性能，评估板结合了一个电源接口的端口IEEE802.3af标准的受电设备（PD）和一个高性能的电流模式开关稳压器。It allows a designer to build PDs with a minimum of external components by means of integrating the required IEEE 802.3af functions and all functions necessary to build a high efficiency DC/DC converter.On the PD side the 34670 fully supports the IEEE802.3af standard and provides the complete signature and power classification functions. It controls inrush current limiting and incorporates adjustable undervoltage lockout. The switching regulator provides excellent line and load regulation. It drives an external power MOSFET with sense resistor.
