● During the test of input reflected ripple current, the input must be connected to an
external input filter (including a 12 μH inductor and a 220 μF electrolytic capacitor),
which is not required in other tests.
● Points B and C are for testing the output voltage ripple.
: The 440 µF aluminum electrolytic capacitor is recommended.
: The 660 µF SMD aluminum solid capacitor or chip aluminum capacitor is recommended
: The 0.1 µF ceramic capacitor is recommended.
: The 10 µF aluminum electrolytic capacitor is recommended.
: The 440 µF aluminum electrolytic capacitor is recommended.
