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. 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-

4mm x 6mm QFN-20 Package
