APPLICATION INFORMATION
capacitor selection (continued)
Tables 3 and 4 lists the manufacturers of recommended capacitors. In most applications surface-mount
tantalum capacitors will be the right choice. However, ceramic capacitors provide the lowest output voltage
ripple due to their typically lower ESR.

power dissipation
The power dissipated in the TPS6013x depends on output current and the mode of operation (1.5x or doubler
voltage conversion mode). It is described by the following equation:
