DESCRIPTION

The MP8007 is an integrated IEEE 802.3af

compatible PoE Powered Device with PD

interface and power converter. It is targeted for

isolated or non-isolated 13W PoE application.

The PD interface has all the functions of IEEE

802.3af,

including

detection,

classification,

120mA inrush current, 840mA 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 primary-side regulation

without opto-coupler feedback in flyback mode

simplifies

the

design

while

buck

mode

continues minimizes the solution size for non-

isolated applications. A 180V integrated power

MOSFET optimizes the device for various wide

voltage applications.

The MP8007 features protection including over

current protection, over voltage protection, open

circuit protection and thermal shutdown.

The MP8007 can support a front-end solution

for PoE-PD application with minimum external

component,

it

is

available

in

QFN-28

(4mmX5mm) package.
