The PD70201EVB-U-25F-5 board is used for evaluating the performance of the PD70201 device in both standard IEEE 802.3at and non-standard applications with input 17-54 V . The board is a 25 W PD consisting of DC isolated DC-DC converter to step down voltage to 5 V. The AUX input gets priority in supplying the load, when it is connected to the application and the PD inputs act as backup power if the AUX is disconnected.The evaluation board provides designers with the environment needed for evaluating the performance and implementation of PD applications based on the PD70201 device. The board uses a single PD device (PD70201ILQ) to support the detection, classification, and power supplying phases on the 2/4 pairs of the Cat5 cable. PD70201ILQ supports a standard IEEE 802.3at Type 2 interface as well as wide range non-standard input voltage.
