MP8007H

Fully Integrated, 802.3af-Compatible PoE

PD Interface with 13W Primary-Side

Regulated Flyback or Buck Converter

DESCRIPTION

FEATURES

The MP8007H is an integrated, IEEE 802.3af-

compatible, PoE-powered device with a PD

interface and power converter. It is targeted for

isolated or non-isolated 13W PoE applications.



Compatible with 802.3af Specifications

Supports 13W PoE Power Applications

300KHz Maximum Switching Frequency

100V 0.48Ω PD Integrated Pass Switch

120mA PD Inrush Current

840mA PD Operation Current Limit

Auxiliary Adapter ORing Power Supply

Integrated 180V Switching Power MOSFET

Supports Primary-Side Regulated Flyback

without Optocoupler Feedback

Supports Low-Side Switch Buck Converter

Up to 3A Programmable Switching Current

Limit

The PD interface has all the functions of IEEE

802.3af, including detection, classification,

120mA inrush current, 840mA operation current

limit, and a 100V hot-swap MOSFET.

The DC/DC converter uses fixed peak current

and

variable

frequency

discontinuous



conduction mode (DCM) to regulate a constant

output voltage. The primary-side regulation

without optocoupler feedback in flyback mode

simplifies the design. Buck mode minimizes the

solution size for non-isolated applications. A

180V integrated power MOSFET optimizes the

device for various wide-voltage applications.



OLP, OVP, Open-Circuit, and Thermal

Protection

Minimal External Components

Available in a QFN-28 (4mmx5mm)

Package



The device’s protection features include over-

current protection, over-voltage protection,

open-circuit protection and thermal shutdown.

APPLICATIONS



IEEE 802.3af-Compliant Devices

Security Cameras

VoIP Phones

WLAN Access Points

IoT Devices

The MP8007H can support a front-end solution

for PoE-PD applications with minimal external

components. It is available in a QFN-28

(4mmx5mm) package.

All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For
