With its high frequency zero voltage switching (ZVS) topology, the DCM converter consistently delivers high efficiency across the input line range. The DCM provides tight output voltage regulation and offers a secondary-referenced control interface for trim, enable, and remote sense operation. DCM converters and downstream DCDC products support efficient power distribution, providing superior power system performance and connectivity from a variety of unregulated power sources to the point-of-load. The VIA package offers flexible thermal management options with very low top and bottom side thermal impedances.
