Output Capacitor Selection
The ESR and ESL of the output capacitor directly control the
output ripple. Use low capacitors with low ESR and ESL at
the output for high efficiency and low ripple voltage. Surface
mount tantalums, surface mount polymer electrolytic and
polymer tantalum, Sanyo- OSCON, or multi-layer ceramic ca-
pacitors are recommended at the output.
The output capacitor of the SEPIC sees very large ripple cur-
rents (similar to the output capacitor of a boost converter. The
rms current through the output capacitor is given by:
