Description

MPL

Optimized Performance with MPS Inductor

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.

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, as well as 100V hot-swap MOSFET.

The flyback/forward controller is specifically designed for both low-cost, small-sized isolated solutions with primary-side regulate (PSR) flyback application, and high-efficiency secondary-side regulation (SSR) active-clamped forward applications. It also can be used in SSR flyback topology.

The MP8009 can support a front-end solution for PoE-PD application with minimal external components. It is available in a QFN-28 (4mmx5mm) package.

Optimized Performance with MPS Inductor

The EVL8009-V-00H is an evaluation board designed to demonstrate the capabilities of the MP8009, an integrated, IEEE 802.3af/at compliant, power over Ethernet (PoE), powered device (PD) power supply converter. It also includes a PD interface and a highly efficient flyback/forward controller.

The PD interface features all IEEE 802.3af/at capabilities, including detection, 1-event classification, 2-event classification, a 120mA inrush current limit, an 840mA operation current limit, and a 100V hot-swap MOSFET. The flyback/forward controller is a cost-effective, small-sized, isolated solution with primary-side regulation (PSR) for flyback applications. It also features high-efficiency secondary-side regulation (SSR) for active-clamp forward applications. The controller can also be used for SSR flyback topologies.

The MP8009 can support a PoE PD front-end solution with minimal external components, and is available in QFN-28 (4mmx5mm) package.
