Application Hints
Table 4. Input Capacitors for Fixed Output Voltage Application
*
No. represents the number of identical capacitor types to be connected in parallel
C Code indicates the Capacitor Reference number in Table 2 for identifying the specific component from the manufacturer.
(Assumes worst case maximum input voltage and load current for a given inductance value)
Check voltage rating of capacitors to be greater than application input voltage.
