DESCRIPTION
EV8008L-V-00A Evaluation Board is designed
to demonstrate the capability of MP8008L`s
function. The MP8008L 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 85mA 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 MP8008L
flyback also features protection including over
load, short output and over voltage protection.
The MP8008L can support a front-end solution
for PoE-PD application, it is available in QFN-
28 (4mmX5mm) package.

Notes:
1) Load current capability is lower than 2.1A when VDD drops
to 36V which is limited by PD input current limit.
2) With 12V adapter input, load capability may be lower than
2.1A which is limilted by input diode temperature rising.
