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 3.3

μF 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.
