Product Description
• Wide input range 160 – 420 Vdc
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 28.0 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.
• Safety Extra Low Voltage (SELV) 28.0 V Nominal Output
• ZVS high frequency switching
• Allows remote sense or local sense operation
• Tight regulation over all line and load conditions
• Fully operational current limit
• OV, OC, UV, short circuit and thermal protection
• Available in chassis mount and through hole VIA package
n 3.750” x 1.400” x 0.370”
The VIA package offers flexible thermal management options
with very low top and bottom side thermal impedances.
