DESCRIPTION

The DCMSAU2 series of DC/DC converters provides 2 Watts of output power in a

miniature SMT package. These converters operate over input voltage ranges of

4.5~5.5VDC, 10.8~13.2VDC, and 21.6~26.4VDC. This series also has single and dual

output voltages of 5V, 12V, ±5V, ±12V, and ±15VDC. The DCMSAU2 series’ impressive

efficiencies enable these modules to deliver their fully rated output power from –40°C to

+80°C without a heatsink or forced-air cooling. The very small footprint of these

converters makes them an ideal solution for many applications where a voltage has to be

isolated such as for noise reduction, ground loop elimination in digital interfaces, or

where a converted voltage is required. These converters are also fully qualified for the

higher temperature profile used in lead-free reflow solder processes. These converters

can also be supplied in tape&reel packaging for use in automated SMD production lines.

NOTES

1. The DCMSAU2 series requires a minimum output loading to maintain specified regulations. Operation under no-load conditions will not

damage these devices; however they may not meet all listed specifications.

2. All DC/DC converters should be externally fused at the front end for protection.

3. Other input and output voltages may be available, please contact factory.

*Due to advances in technology, specifications are subject to change without notice.
