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.

DESIGN CONSIDERATIONS
Input Reflected-Ripple Current Test Setup
Input reflected-ripple current is measured with an inductor Lin (4.7µH) and Cin (220µF, ESR < 1.0Ω at 100 KHz) to simulate
source impedance. Capacitor Cin offsets possible battery impedance. Current ripple is measured at the input terminals of the
module. Measurement bandwidth is 0-500 KHz.
Peak-to-Peak Output Noise Measurement Test
Use a 0.33µF ceramic capacitor. Scope measurement should be made by using a BNC socket, measurement bandwidth is 020MHz. Position the load between 50mm and 75mm from the DC/DC converter.
TEST SETUP
Maximum Capacitive Load
The DCMSAU1 series has a limitation of maximum connected capacitance on the output. The power module may be
operated in current limiting mode during start-up, affecting the ramp-up and the start-up time. The maximum capacitance can
be found in the Model Selection Table.
Input Source Impedance
The power module should be connected to a low ac-impedance input source. Highly inductive source impedances can affect
the stability of the power module. In applications where power is supplied over long lines and output loading is high, it may be
necessary to use a capacitor at the input to ensure startup. Capacitor mounted close to the power module helps ensure
stability of the unit, it is recommended to use a good quality low Equivalent Series Resistance (ESR < 1.0Ω at 100 KHz)
capacitor of 2.2µF for 5VDC input models, 1.0µF for 12VDC input models, and 0.47µF for 24VDC input models.
Output Ripple Reduction
A good quality low ESR capacitor placed as close as possible across the load will give the best ripple and noise performance.
To reduce output ripple, it is recommended to use 1.5µF capacitors at the output.

TEST SETUP
Thermal Considerations
Many conditions affect the thermal performance of the power module, such as orientation, airflow over the module, and board
spacing. To avoid exceeding the maximum temperature rating of the components inside the power module, the case
temperature must be kept below 90°C. The derating curves are determined from measurements obtained in a test setup.
