8.2.5 Output Capacitor Selection
For best output voltage filtering a low ESR output capacitor is recommended. Typically, four 10-μF (or two 22-μF) ceramic output capacitors work for most of the applications. Higher capacitor values can be used to improve the load transient response. A 10 μF capacitor is also required between the rectifier diode and the SWI pin (Refer to the Recommended Operation Conditions table, Table 8-3 and the Typical Application section for output capacitor recommendations).
Table 8-3 Input and Output Capacitor Selection Boost / Buck 1
| CAPACITOR | VOLTAGE RATING | COMPONENT SUPPLIER | COMPONENT CODE | COMMENTS |
|---|---|---|---|---|
| 1μF/0603 | 16V | Taiyo Yuden | EMK107BJ105KA | AVIN bypass |
| 10μF/1206 | 16V | Taiyo Yuden | EMK212BJ106KG | CIN |
| 10μF/1206 | 25V | Taiyo Yuden | TMK316BJ106KL | COUT |
| 22μF/1210 | 25V | Murata | GRM32ER61E226KE15 | CIN / COUT |
To calculate the output voltage ripple, the following equations can be used:
Equation 1. 
?VC_ESR can be neglected in many cases since ceramic capacitors provide very low ESR.
