DU SERIES APPLICATION NOTES:

EXTERNAL CAPACITANCE REQUIREMENTS:

No external capacitance is required for operation of the DU series.

To meet the reflected ripple requirements of the converter,an input impedance of less than 0.5 ohm

from DC to 100KHz is required.

External output capacitance is not required for operation,however it is recommended that 10uF

tantalum and 0.1uF ceramic capacitance be selected for reduced system noise.

Additional output capacitance may be added for increased filtering,but should not exceed 220uF.
