Capacitor Selection
Ceramic capacitors such as X5R or X7R
are recommended to be used with the
YB1315. 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
YB1315.
