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 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. The VIA package offers flexible thermal management options with very low top and bottom side thermal impedances.

The internal safety approved isolating component (ChiP) provides reinforced insulation (4242 V) from the input to output. However, the VIA package itself can only be tested at a basic isolation value (2121 V). See Dielectric Withstand Test section on page 15 and Dielectric Withstand section on page 18 for more details.
