Monolithic Power Systems MP8017 | Demoboard EVL8017-L-00B

Beschreibung

The EVL8017-L-00B is an evaluation board designed to demonstrate the capabilities of the MP8017, an integrated, IEEE 802.3afcompatible, power over Ethernet (PoE) powered device (PD). The device also includes a PD interface and a flyback power converter. The MP8017 provides a front-end solution for small-sized, 13W, isolated PoE applications. The PD interface features IEEE 802.3af capability. The MP8017 flyback converter is specifically designed for active-clamp, primary side regulation (PSR) in a flyback topology, which supports small size and high efficiency. The MP8017 can also be set to secondary side regulation (SSR) for active-clamp flyback topologies. It is recommended to read the MP8017 datasheet prior to making any changes to the EVL8017-L-00B.
