Product Description

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.

13W 802.3af PoEPowered Device Interface with Flyback DC/DC Converter

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.
