With its high frequency n Enables low-profile, high-density filtering zero voltage switching (ZVS) topology, the DCM converter Optimized for array operation consistently delivers high eciency across the input line range. Modular DCM converters and downstream DC-DC products n Up to 8 units 4000 W support ecient power distribution, providing superior power n No power derating needed system performance and connectivity from a variety of n Sharing strategy permits dissimilar line voltages unregulated power sources to the point-of-load. across an array Leveraging the thermal and density benets of Vicors ChiP Fully operational current limit packaging technology, the DCM module oers exible thermal management options with very low top and bottom side OV, OC, UV, short circuit and thermal protection thermal impedances. Thermally-adept ChiP based power 4623 through-hole ChiP package components enable customers to achieve cost eective power system solutions with previously unattainable system size, n 1.886 x 0.898 x 0.286 weight and eciency attributes, quickly and predictably.
