MONOLITHIC POWER SYSTEMS (MPS) MP8009GV-P

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 and a 100V hotswap 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 for active clamped forward applications. It can be used in SSR flyback topologies. It provides hiccup protection for overload protection, short-circuit protection, overvoltage protection and thermal shutdown. It is available in a QFN-28 (4mmx5mm) package. Applications include IEEE 802.3af/at-compliant devices, security cameras, video telephones, WLAN access points, internet-of-things (IoT) devices.
