The most common application for these devices is a charge-pump voltage inverter (see Figure 9-1). This application requires only two external components; capacitors C(fly) and CO, plus a bypass capacitor, if necessary. Refer to the capacitor selection section for suggested capacitor types.
For the maximum output current and best performance, three ceramic capacitors of 1 µF (TPS60400, TPS60403) are recommended. For lower currents or higher allowed output voltage ripple, other capacitors can also be used. It is recommended that the output capacitors has a minimum value of 1 µF. With flying capacitors lower than 1 µF, the maximum output power decreases.
