DESCRIPTION
EV8008-V-00A Evaluation Board is designed to
demonstrate the capability of MP8008`s
function. The MP8008 is an integrated IEEE
802.3af/at PoE compliant Powered Device (PD)
power supply converter. It includes PD interface
and peak current mode flyback controller.
The PD interface has all the functions of IEEE
802.3af/at, and sets 120mA inrush current limit,
840mA operation current limit as well as 100V
Hot-swap MOSFET.
The flyback PWM controller can drive an
external MOSFET capable of handling more
than 10A current. PSM function improves the
efficiency in light load condition. The MP8008
flyback also features protection including over
load, short output and over voltage protection.
The MP8008 can support a front-end solution
for PoE-PD application, it is available in QFN-
28 (4mmX5mm) package.
