Input and Output Filter Capacitors

Choose input and output filter capacitors that will service the input and output peak currents with acceptable voltage

ripple. Choose input capacitors with voltage ratings greater than the maximum input voltage, and output capacitors

with voltage ratings greater than the output voltage.
