Charge Pump Flying Capacitor (C5)
The value and ESR of the hold capacitor (C5) directly affects the ripple on CPV
Decreasing the ESR of C5 reduces both output ripple and charge pump output impedance. A lower value capacitor can be used
in systems with low maximum output power requirements. Please refer to the demonstration board schematic shown in Figure 27.
