Isolated, Regulated DC Converter
Features & Benefits
• Isolated, regulated DC-DC converter • Up to 120 W, 5.00 A continuous • 90.6% peak efficiency • 532 W/in3 Power density • Wide input range 43 – 154 Vdc • Safety Extra Low Voltage (SELV) 24.0 V Nominal Output • 3000 Vdc isolation • ZVS high frequency switching
n Enables low-profile, high-density filtering • Dual modes of operation:
n Array mode – Up to 8 units – 960 W – No power derating needed – Sharing strategy permits dissimilar line voltages across an array
n Enhanced VOUT regulation mode – Standalone: 120 W
• Fully operational current limit • OV, OC, UV, short circuit and thermal protection • 2322 through-hole ChiP™ package
n 0.978” x 0.898” x 0.284” (24.84 mm x 22.8 mm x 7.21 mm)
Typical Applications
• Rail Transportation • Defense / Aerospace • Industrial • Process Control

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.
