MP8009

Fully-Integrated 802.3af/at Compliant PoE PD Interface with High Efficiency Flyback/Forward Controller

Description

The MP8009 is an integrated IEEE 802.3af/at PoE compliantPowered Device (PD) power supply converter. It includes PD interface and 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 size isolated solution with primary-side regulate (PSR) flyback application, and high efficiency secondary-side regulate (SSR) active-clamped forward application. It also can be used in SSR flyback topology.

The MP8009 can support a front-end solution for PoE-PD application with minimum external components. It is available in QFN-28 (4mmX5mm) package.
