Capacitor Selection
Ceramic capacitors such as X5R or X7R are recommended to be used with the YB1313. For the two
flying capacitors C1 and C2, it is important to use low ESR capacitors to avoid unnecessary
efficiency losses. Low ESR capacitors on VOUT reduce the ripple voltage on the supply of the
current sources. Table 5 lists capacitor types that have been tested with the YB1313.
