Product Description
The DCM Isolated, Regulated DC Converter is a DC-DC
converter, operating from an unregulated, wide range input to
generate an isolated 12.0 Vdc output. With its high frequency
zero voltage switching (ZVS) topology, the DCM converter
consistently delivers high efficiency across the input line range.
Modular DCM converters and downstream DC-DC products
support efficient power distribution, providing superior power
system performance and connectivity from a variety of
unregulated power sources to the point-of-load.
Leveraging the thermal and density benefits of Vicor’s ChiP
packaging technology, the DCM module offers flexible thermal
management options with very low top and bottom side
thermal impedances. Thermally-adept ChiP based power
components enable customers to achieve cost effective power
system solutions with previously unattainable system size,
weight and efficiency attributes, quickly and predictably.
