Understanding Power over Ethernet and PoE Controllers and Converters

Explore what Power over Ethernet (PoE) Means for Your Design

This introduction to power over Ethernet (PoE) covers the basics of PoE standards, how PoE structure functions, and how PoE works between the PSE and PD. PoE enables an Ethernet cable to transmit DC power while also transmitting data in parallel to IP terminal devices. PoE power delivery includes two equipment types: Power-sourcing equipment (PSE) or a power provider, and powered devices (PDs) or power receivers. MPS offers complete PoE solutions, including PD controllers, isolated DC/DC converters, non-isolated DC/DC converters, PD controllers integrated with DC/DC converters, and PSE controllers, covering power requirements from 13W to 71W.
