Monolithic Power Systems MP8009 | Demoboard EVL8009-V-00H

Description

The EVL8009-V-00H is an evaluation board designed to demonstrate the capabilities of the MP8009, an integrated, IEEE 802.3af/at 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 low-cost,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.
