APPLICATION CIRCUIT
TECHNICAL NOTES
The OM955X Series design includes on-board input and output filtering
(22uF input capacitor and a 330uF output capacitor are included in the
design). However some applications could require a further reduction in
ripple/noise parameters. The optional by-pass capacitors shown above can
be used if an improvement in switching noise is necessary in your
application. If ripple reduction is also necessary, additional tantalum
capacitors may be added to the output. Capacitors should be low ESR and
have a voltage rating of 10V minimum.
