Description
The DCM is an isolated, highly efficient, regulated DC-DC converter
utilizing high frequency zero-voltage switching (ZVS) topology,
operating from an unregulated, wide range input to generate an
isolated output. 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 ChiP module offers flexible thermal management options
with very low top and bottom side thermal impedances while the
DCM VIA module additionally provides integrated EMI filtering,
tight output voltage regulation, and a secondary-referenced
control interface while retaining the fundamental design benefits
of the conventional brick architecture.
