Recommended circuit
If you want to further decrease the input/output
ripple, an “LC” filtering network may be connected
to the input and output ends of the DC/DC
converter, see (Figure 1).
KHz
*Test ripple and noise by “parallel cable” method. See detailed operation instructions at Testing
of Power Converter section, application notes.
Note:
1. All specifications measured at TA=25°C, humidity<75%, nominal input voltage and rated
output load unless otherwise specified.
