MPS MP8007GV-Z

Контроллер (PD), DC/DC13 W802.3af (PoE)

Overview

The MP8007GV-Z is an integrated IEEE 802.3af compatible PoE Powered Device with PD interface and power converter. It is targeted for isolated or non-isolated 13W PoE application.The PD interface has all the functions of IEEE 802.3af, including detection, classification, 120mA inrush current, 840mA operation current limit as well as 100V Hot-swap MOSFET.The DCDC converter uses fixed peak current and variable frequency discontinuousconduction mode (DCM) to regulate constant output voltage. The primary-side regulation without opto-coupler feedback in flyback mode simplifies the design while buck mode continues minimizes the solution size for non-isolated applications. A 180V integrated power MOSFET optimizes the device for various wide voltage applications.The MP8007GV-Z features protection including over current protection, over voltage protection, open circuit protection and thermal shutdown.The MP8007GV-Z can support a front-end solution for PoE-PD application with minimum external component, it is available in QFN-28 (4mmX5mm) package. Bostock Electronics is an authorized Monolithic Power Systems distributor.
