Product Information

Back to top
The MP8008 is an integrated, IEEE, 802.3af/at, PoE-compliant, powered device (PD), power supply converter. The MP8008 includes PD interface and a peak-current-mode flyback 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 hot-swap MOSFET.

The flyback PWM controller can drive an external MOSFET capable of handling more than 10A of current for high-powered flyback PoE applications. Pulse-skipping mode function improves efficiency in light-load condition. The MP8008 flyback features protections including overload protection (OLP), short output, and over-voltage protection (OVP).

The MP8008 can support a front-end solution for PoE PD applications with minimum external components and is available in a QFN-28 (4mmx5mm) package.

Applications
• IEEE 802.3af/at-Compliant Devices
• Security Cameras
• Video Telephones
• WLAN Access Points
• IoT Devices
