DESCRIPTION

EV8007-V-00D 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.
