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 3.3V, 5V, 12V, ±5V, ±12V, and ±15VDC. The MSLU2 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.

The MSLU02 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. It is not recommended to use water-washing processes on SMT units. 4. Other input and output voltages may be available, please contact factory. *Due to advances in technology, specifications are subject to change without notice. 09/26/2013 Wall Industries, Inc. • 37 Industrial Drive, Exeter, NH 03833 • Tel: 603-778-2300 • Toll Free: 888-597-9255 • Fax 603-778-9797 website: www.wallindustries.com • e-mail: [email protected] Page 1 of 5 Rev A MSLU02 SERIES 2 Watt DC/DC Power Converters SPECIFICATIONS: MSLU02 SERIES All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted.

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 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. Maximum Capacitive Load The MSLU02 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. 09/26/2013 Wall Industries, Inc. • 37 Industrial Drive, Exeter, NH 03833 • Tel: 603-778-2300 • Toll Free: 888-597-9255 • Fax 603-778-9797 website: www.wallindustries.com • e-mail: [email protected] Page 4 of 5 Rev A MSLU02 SERIES 2 Watt DC/DC Power Converters 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. DERATING CURVE COMPANY INFORMATION Wall Industries, Inc. has created custom and modified units for over 50 years.
