Output Ripple Reduction

A good quality low ESR capacitor placed as close as

practicable across the load will give the best ripple and noise

performance.

To reduce output ripple, it is recommended to use 4.7uF

capacitors at the output.

Maximum Capacitive Load

The MKW2500 series has limitation 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 optimum performance we recommend 220uF

capacitive load for single outputs.

The maximum capacitance can be found in the data sheet.

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 100°C.

The derating curves are determined from measurements

obtained in an experimental apparatus.
