Product Description

EV8007-V-00C Evaluation Board is designed to demonstrate the capability of MP8007`s primary-side regulate fly-back function. This board supports IEEE 802.3af PoE compliant Powered Device with PD interface and flyback power converter. It is targeted for isolated 13W PoE application.

The PD interface has all the functions of IEEE 802.3af, including detection, classification, inrush current, operation current limit as well as 100V Hot-swap MOSFET. The DCDC converter uses fixed peak current and variable frequency discontinuous conduction mode (DCM) to regulate constant output voltage.

The MP8007 is available in QFN-28 (4mmX5mm ) package.
