VICOR DCM™ DC-DC Converter DCM2322x50T1360y6z Isolated, Regulated DC Converter Product Ratings The DCM2322 is a lower-power, isolated and regulated DC-DC converter that operates from an unregulated, wide-range input to generate an isolated 12.0VDC 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. Features & Benefits • Isolated, regulated DC-DC converter • Wide input range 9 - 50VDC • Safety Extra Low Voltage (SELV) 12.0V nominal output ■ Enables low-profile, high-density filtering • Dual modes of operation: - No power de-rating needed - Sharing strategy permits dissimilar line voltages across an array ■ Enhanced VOUt regulation mode • Fully operational current limit • OV, OC, UV, short circuit and thermal shut down Typical Applications • Rail Transportation • Defense / Aerospace • Process Control Product Description Leveraging the thermal and density benefits of Vicor 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.
