DESCRIPTION

The MP6004 is a monolithic flyback dc-dc

converter with a 180 V power switch that

targets isolated or non-isolated 13 W PoE

applications. It supports both primary-side

regulated

flyback

and

high-voltage

buck

applications.

MP6004 uses 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 180 V integrated power

MOSFET optimizes the device for various wide

voltage applications.

The 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.
