DESCRIPTION
The MSLU series power modules are 1W DC/DC converters 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, 9, 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 heatsink 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: MSLU Series
All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted.

NOTES
1. The MSLU 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 max 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 3000VDC I/O isolation voltage see the MSLUH series.

DESIGN & FEATURE CONSIDERATIONS
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 MSLU 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. For optimal performance we recommend a
maximum load of 33µF.
TEST CONFIGURATIONS
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 100KHz) 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 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 3.3μF 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.
