DCM™ DC-DC Converter DCM2322x50T1360y6z Isolated, Regulated DC Converter Features & Benefits Product Ratings • Isolated, regulated DC-DC converter • Up to 60W, 5.00A continuous • 89.7% peak efficiency • 241W/in3 power density Product Description • Wide input range 9 – 50VDC • Safety Extra Low Voltage (SELV) 12.0V nominal output • 3000VDC isolation • ZVS high-frequency switching Enables low-profile, high-density filtering • Dual modes of operation: Array mode – Up to 8 units – 480W – No power de-rating needed – Sharing strategy permits dissimilar line voltages across an array Enhanced VOUT regulation mode – Standalone 60W 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. 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. • Fully operational current limit • OV, OC, UV, short circuit and thermal shut down Typical Applications Package Information • Through-hole ChiP™ package 0.978 x 0.898 x 0.284in [24.84 x 22.80 x 7.21mm] • Rail Transportation • Defense / Aerospace • Industrial • Process Control Note: Product images may not highlight current product marking
