Upgrade to myMPS+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.

IC Details
The MP8004 is an integrated IEEE 802.3af PoE compliant Powered 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 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, auto-retry, and incorporates over current, short circuit, and over voltage protection. It can also skip cycles to maintain zero load regulation. The MP8004 can support a front-end solution for PoE-PD application with minimum external components, and is available in thermally enhanced 4x6mm QFN20 package.
