APPLICATION NOTES CONTINUED

Output Ripple Reduction

By using the values of inductance and capacitance stated, the output ripple at the

rated load is lowered to 5mV p-p max.

Component selection

Capacitor: It is required that the ESR (Equivalent Series Resistance) should be

as low as possible, ceramic types are recommended. The voltage rating should

be at least twice (except for 15V output), the rated output voltage of the DC/DC

converter.

Inductor: The rated current of the inductor should not be less than that of the

output of the DC/DC converter. At the rated current, the DC resistance of the

inductor should be such that the voltage drop across the inductor is <2% of the

rated voltage of the DC/DC converter. The SRF (Self Resonant Frequency) should

be >20MHz.
