Product Description
The DCM in a VIA package is an Isolated, Regulated DC-to-DC
Converter, operating from an unregulated, wide range input to
generate an isolated 48.0 Vdc output. 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.

Enables and disables trim functionality. Adjusts output voltage when trim active.
Negative sense pin, required for Remote Sense Operation. In Local Sense
Operation, it can be tied directly to –OUT to achieve better regulation accuracy.
Positive sense pin, required for Remote Sense Operation. In Local Sense
Operation, it can be tied directly to +OUT to achieve better regulation accuracy.
Note:
All control inputs (EN, TR, –SENSE, +SENSE) are referenced to the secondary of the DCM and isolated from the primary.

The absolute maximum rating listed above for Dielectric withstand (input to output) refers to the internal safety approved isolating component (VI ChiP)
that provides the reinforced insulation from input to output. The VIA package itself can only be tested at a basic insulation value (2121 V). See Dielectric
Withstand Test section on page 15 and Dielectric Withstand section on page 18 for more details.
