Product Description
The DCM2322 is a lower power, isolated and regulated DC-DC
converter that operates from an unregulated, wide-range input
to generate an isolated 24.0 Vdc output. With its high-frequency
zero-voltage switching (ZVS) topology, the DCM2322 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 DCM2322 offers flexible thermal
management options with very low top and bottom side
thermal impedances. Thermally adept ChiP based power
components enable customers to quickly and predictably
achieve cost effective power system solutions.
