MP8008

Fully Integrated, 802.3af/at-Compliant, PoE PD Interface with a Peak-Current-Mode Flyback Controller

Datasheet

概要

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.

Evaluation Tools

EV8008-V-00A Evaluation Kit Fully Integrated IEEE 802.3af/at-Compliant PoE PD Interface with Peak Current Mode Flyback Controller Evaluation Board

The EV8008-V-00A evaluation board is designed to demonstrate the capability of the MP8008, which is an integrated IEEE 802.3af/at PoE-compliant powered device (PD) power supply converter. It includes a PD interface and peak current mode flyback controller.

The PD interface has all the functions of IEEE 802.3af/at, and sets 120mA inrush current limit, 840mA operation current limit as well as a 100V hot-swap MOSFET. The flyback PWM controller can drive an external MOSFET capable of handling more than 10A of current. The PSM function improves the efficiency in light-load conditions.

The MP8008 flyback features overload, short output, and over=voltage protections. The MP8008 can support a front-end solution for PoE-PD application, and is available in a QFN-28 (4mmx5mm) package.
