FEATURES

DESCRIPTION

The DCMSAU1 series of DC/DC converters provides 1 Watt of output power in an SMT

package featuring high I/O isolation of 3000VDC. 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, 15V, ±5V, ±12V, and ±15V. The DCMSAU1 series’ impressive

efficiencies enable these modules to deliver their fully rated output power from –40°C to +85°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 higher I/O isolation 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 DCMSAU1 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.
