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.

Maximum Capacitive Load

The LANCW3 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.

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.
