1 Isolated, Regulated DC ConverterDCM in a VIA PackageDC-DC ConverterFeatures & Benefits Isolated, regulated DC-to-DC Converter Up to 320 W, A continuous peak efficiency 211 W/in3 Power density Wide input range 16 50 Vdc Safety Extra Low Voltage (SELV) 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 x x ( mm x mm x mm)

2 Typical Applications Industrial Process Control Heavy Equipment Defense / AeorspaceProduct DescriptionThe DCM in a VIA Package is an Isolated, Regulated DC-to-DCConverter, operating from an unregulated, wide range input togenerate an isolated output. With its high frequencyzero voltage switching (ZVS) topology, the DCM converterconsistently delivers high efficiency across the input line DCM provides tight output voltage regulation and offers asecondary-referenced control interface for trim, enable, andremote sense operation.

3 DCM converters and downstream DC-DC products support efficient power distribution, providingsuperior power system performance and connectivity from avariety of unregulated power sources to the VIA Package offers flexible thermal management optionswith very low top and bottom side thermal impedances.
