产品描述

The MP8004 is an integrated IEEE 802.3af PoE compliantPowered Device (PD) power supply solution. It includes a PD interface and an isolated/non-isolated flyback converter.

The PD interface includes detection and classification modes as well as a 100V output pass device. An inrush current limit is included to charge the input capacitor slowly without interruption due to die heating.

The DC/DC converter includes a 150V power switch and is capable of delivering 13W PoE power with high efficiency. It has an internal soft start and auto-retry. Also, it incorporates over-current, short-circuit, and over-voltage protection. It can also skip cycles to maintain zero load regulation.

The MP8004 supports a front-end solution for PoE-PD application with minimal external components and is available in a thermally enhanced  4mm x 6mm QFN-20 package.

13W 802.3af PoE Powered Device Interface with Flyback DC-DC Converter EV Board

The MP8004 is an integrated IEEE 802.3af PoE compliantPowered Device (PD) power supply solution. It includes a PD interface and an isolated/non-isolated flyback converter.

The PD interface includes detection and classification modes as well as a 100V output pass device. Inrush current limit is included to slowly charge the input capacitor.

The DC-DC converter includes a 150V power switch and is capable of delivering 13W output power with high efficiency. It has an internal soft-start, auto-retry, over current, short circuit, and over voltage protection. It can also skip cycles during light load condition.

The MP8004 is available in thermally enhanced 4x6mm QFN20 package.
