MP8008

Fully Integrated, 802.3af/at-Compliant,

PoE, PD Interface with a

Peak-Current-Mode Flyback Controller

DESCRIPTION

FEATURES



Compatible with 802.3af/at Specifications

100V, 0.48Ω, PD Integrated Pass Switch

120mA PD Inrush Current

840mA PD Operation Current Limit

Auxiliary Adapter O-Ring Power Supply

PD Power Good and Type-2 PSE Indicator

12V, 1A, Flyback MOSFET Gate Driver

Pulse-Skipping Operation in Light Load

Programmable Switching Frequency: 30kHz

- 400kHz

The MP8008 is an integrated, IEEE, 802.3af/at,

PoE-compliant, powered device (PD), power

supply converter. The MP8008 includes PD

interface and a peak-current-mode flyback

controller.

The PD interface has all the functions of IEEE

802.3af/at, including detection, 1-event and 2-

event classification, 120mA inrush current limit,

840mA operation current limit, and a 100V hot-

swap MOSFET.



Frequency Synchronizing from 80kHz -

400kHz

The flyback PWM controller can drive an

external MOSFET capable of handling more

than 10A of current for high-powered flyback

PoE applications. Pulse-skipping mode function

improves efficiency in light-load condition. The

MP8008 flyback features protections including

overload protection (OLP), short output, and

over-voltage protection (OVP).



Cycle-by-Cycle Current Limit

Overload, Short Circuit, Over-Voltage, and

Thermal Protection



Available in a QFN-28 (4mmx5mm)

Package

APPLICATIONS

The MP8008 can support a front-end solution

for PoE PD applications with minimum external

components and is available in a QFN-28

(4mmx5mm) package.
