(1) These values are recommended values that have been successfully tested in several applications. Other values may be acceptable in
other applications but should be fully tested by the user.
(2) For a two cell Li-ion battery application or input supply above 6 V as shown in Figure 2 , C3 is needed for the internal pre-regulator.
Otherwise, C3 is not needed as shown in Figure 1 .
