Optimizing Capacitor Selection
Refer to
Figure 1
for the total output resistance for various capacitance values and oscillator frequencies.
The reservoir and charge pump capacitor values are equal. The capacitance values required to maintain
comparable ripple and output resistance typically diminish proportionately as the pump frequency of
the
SP6661
increases.
