Output Capacitor Selection
(Continued)
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
capacitors are recommended at the output.
The output capacitor of the SEPIC sees very large ripple
currents (similar to the output capacitor of a boost converter.
The rms current through the output capacitor is given by:
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
capacitors are recommended at the output for low ripple.
