DESCRIPTION
The MSLUH series power modules are 1W DC/DC converters that are specially designed to provide high levels of isolation (3000VDC) in a
miniature “gull-wing” 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 3.3, 5, 12, 15, ±5, ±12, and ±15VDC. These converters impressive
efficiencies enable them to deliver their fully rated output power from –25°C to +75°C without a heat sink or forced-air cooling. These
converters are useful for a variety of applications including distributed power systems, data communication equipment, telecommunication
equipment, and industrial robot systems.
SPECIFICATIONS: MSLUH Series

NOTES
1. The MSLUH 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. Efficiency: typical value measured at full load.
3. All DC/DC converters should be externally fused at the front end for protection.
4. Other input and output voltages may be available, please contact factory.
5. It is not recommended to use water-washing processes on surface mount units.
6. For 1500VDC I/O isolation voltage see the MSLU series.
*Due to advances in technology, specifications are subject to change without notice.

DESIGN & FEATURE CONSIDERATONS
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. A 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 100KHz)
capacitor of 2.2μF for the 5V input models, a 1.0μF for the 12V input models, and a 0.47μF for the 24V input models.

Maximum Capacitive Load
The MSLUH series has a limit of maximum connected capacitance at the output. The power module may be operated in
current limiting mode during start-up, affecting the ramp-up and the startup time. The maximum capacitance can be found in
the Model Selection Table.
TEST CONFIGURATIONS
Peak-to-Peak Output Noise Measurement Test
Use a Cout 0.33μF ceramic capacitor.
Scope measurement should be made by using a BNC socket; measurement bandwidth is 0 ~ 20MHz. Position the load
between 50mm and 75mm from the DC/DC Converter.

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 1.0μF capacitors at the output.

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 an experimental
apparatus.
