DER-097: 48V @ 450mA, 85 ~ 265VAC in

This document is an engineering report describing a Power over Ethernet (PoE) power supply utilizing TOP246P. The power supply delivers 21.7 W continuous from an input of 85 to 265 VAC.

This document provides complete design information including specification, schematic, bill of material and transformer design and construction information. The document also provides performance information.

Although this board is designed to satisfy safety isolation requirements, the engineering prototype has not been agency approved. Therefore, all testing should be performed using an isolated source to provide power to the prototype board.
