            PD70201 Evaluation Board
                    Microchip's IEEE 802.3at evaluation board featuring PD70201 device with an isolated flyback converter
    

The PD70201EVB25F-5 evaluation board from Microchip Technology provides designers with the environment needed for evaluating the performance and implementation of power distribution applications based on the PD70201 device. The board uses a single power distribution (PD) device, PD70201ILQ, to support the detection, class, and power supplying phases on the 2/4 pairs of the Cat5 cable. PD70201ILQ supports a standard IEEE 802.3at Type 2 interface.

The PD70201 is an integrated powered device (PD) interface with PWM controllers for a DC-DC converter used in IEEE 802.3af and IEEE 802.3at applications. The PD70201 can be used for IEEE 802.3af, IEEE 802.3at Type 1, and IEEE 802.3at Type 2 applications. A single PD70201 can be used in 4-pair applications which consumes up to 47.7 W. The PD70201 is ideal for IP, security camera, infrastructure, and power distribution applications.
