the input voltage ripple. The magnetic beads
L2 & L3 are not necessary, but they help to
reduce the high frequency ringings on the in-
put supply significantly. See Figure 5 for de-
tails.
Rsnb2 and Csnb2 can be used to form RC
snubber circuits on the switching nodes,
which may help to reduce the output ripple.
Please refer to the datasheet.
