3. Summary

As a starting point, calculate the RC filter attenuation factor to reduce the ripple current before selecting the final

output capacitor. The variations in system components, specifically the LED load, determine the final LED driver

specifications and tolerances. Designers need to be aware that they have to account for this and use analytical and

empirical evaluation to ensure that their designs meet specification.
