If the measured output voltage ripple is too high for the application, improvements can be made. The first step
is to increase the capacitance at the output. If the ripple is still too high, the second step would be to increase
the capacitance at the input. For lower output currents, lower value flying capacitors can be used. Tables 3 and
4 lists the manufacturers of recommended capacitors.
