MSKUW Datasheet, PDF (7/7 Pages) Wall Industries,Inc. – 5 Watt DC/DC Converter Single and Dual Outputs

Rev A
MSKUW Series
5 Watt DC/DC Converter
Single and Dual Outputs
4:1 Ultra Wide Input Voltage Range
Peak-to-Peak Output Noise Measurement Test
Use a Cout 0.47µF 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.
