DESCRIPTION
The DCMSW1 series of DC/DC converters provides 1 Watt of output power in an ultra compact
SMT package. These converters operate over 2:1 input voltage ranges of 4.5-9VDC, 9-18VDC,
18-36VDC, and 36-75VDC. This series also has fully regulated single and dual output voltages
of 5V, 12V, 15V, ±12V, and ±15V. The DCMSW1 series’ impressive efficiencies enable these
modules to deliver their fully rated output power from –40°C to +75°C without derating. Other
features include remote on/off control, low ripple and noise, 1500VDC I/O isolation, and
continuous short circuit protection. The very small footprint of these converters makes them an
ideal solution for space critical applications in communication equipment, instrumentation, and
many other battery operated applications.
