Microchip Technology's PD70201EVB47F evaluation board provides designers with an environment needed to evaluate the performance and implementation of PD applications based on the PD70201 device. The board is using a single PD device (PD70201ILQ) to support the detection, class and power supplying phases on the 4 pairs of the Cat5 cable. The PD70201ILQ supports the current of the four-pairs, which is twice the level of a standard IEEE 802.3at Type 2 interfaces.
The PD70201 is a powered device interface integrated with PWM controllers for a DC/DC converter used in IEEE802.3af and IEEE802.3at applications. The PD70201 can be used for IEEE802.3af/IEEE802.3at Type 1 applications, and in IEEE802.3at Type 2 applications. A single PD70201 can be used in four-pair applications which consumes up to 47.7 W. This device has several features designed to improve efficiency and reliability. The PD70201 device is ideal for network camera, swappable power supply, and telecom applications.
