MP6004

The MP6004 is a monolithic flyback DC/DC converter with a 180V power switch that targets isolated or non-isolated 13W PoE applications. It supports both primary-side regulated flyback and high-voltage buck applications. The MP6004 uses a fixed peak current and variable frequency discontinuous conduction mode (DCM) to regulate constant output voltage. The primary-side regulation without opto-coupler feedback in flyback mode simplifies the design and saves BOM cost while buck mode minimizes the solution size for non-isolated applications. A 180V integrated power MOSFET optimizes the device for various wide voltage applications. MP6004 protection features include over-load protection, over-voltage protection, open-circuit protection, and thermal shutdown. The MP6004 is available in a QFN-14 3mm x 3mm package.
