Data Sheet - Application Information
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.
