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

Description

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