MP8009

Fully Integrated, 802.3af/at Compliant

PoE PD Interface with High-Efficiency

Flyback/Forward Controller

DESCRIPTION

FEATURES

The MP8009 is an integrated IEEE 802.3af/at

PoE compliant powered device (PD) power

supply converter. It includes a PD interface and

a high-efficiency flyback/forward controller.



Compatible with 802.3af/at Specifications

100V, 0.48Ω PD Integrated Pass Switch

120mA PD Inrush Current

840mA PD Operation Current Limit

Supports >8.5V Auxiliary Adapter Supply

Supports Flexible Topology Design:

o Primary-Side Regulation (PSR) for

Flyback Applications

o Secondary-Side Regulation (SSR) for

Flyback Applications

o SSR for Active Clamp Forward

Applications

2A GATE and 0.8A SYNC Drivers

160mV Switching Current-Sense Limit

Output Diode Compensation in PSR Mode

250kHz Fixed Switching Frequency

EMI Reduction with Frequency Dithering

Available in a QFN-28 (4mmx5mm)

Package

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.

The flyback/forward controller is specifically

designed to be cost-effective. It is a space-

saving isolated solution with primary-side

regulation (PSR) for flyback applications, and

high-efficiency secondary-side regulation (SSR)

for active clamped forward applications. It can

be used in SSR flyback topologies.



The MP8009 can support a front-end solution

for PoE PD applications with a minimal number

of external components. It provides Hiccup

Protection for Overload Protection (OLP),

Short-Circuit Protection (SCP), Over-Voltage

Protection (OVP), and Thermal Shutdown. It is

available in a QFN-28 (4mmx5mm) package.

APPLICATIONS
