for Input Reflected Ripple Current and Output Voltage
Ripple.
Figure 7. Input reflected ripple current at nominal input
voltage and rated load current (see Fig.6)
Figure 8. Output voltage ripple at nominal input voltage and
rated load current. Load cap: 20

** see note below (see Fig.6)
**Output ripple measure: care must be taken to insert the output capacitors in the output current paths.
The measurements is taken with the following output capacitors:
-2x AVX PN CM316X5R106K006AT
-2x Murata PN GRM31CR60J106KC01L
-2x Taiyo Yuden PN JMK316B106KL
