Inductor Selection:
Different inductor values and/or from different manufacturers
can be used in place of what is shown. However, the circuit will
need to be reoptimized by changing the R
value. Smaller
R
SW-OSC
value needs to be used for inductors with lower series
resistance. Lower amount of current will be drawn when using
larger value inductors. But, for the same R
value, a lower
amount of energy will be transferred due to the higher series
resistance of a larger value inductor. Hence, when larger value
inductors with higher series resistance are used, the R
value needs to be increased. It is very important to make a note
of the saturation current of the inductor. If the saturation current
of the inductor is lower than what the circuit/application requires,
the inductor and/or IC will be damaged.
C
S
Capacitor Selection:
Different C
S
Capacitor types and value can be used in place of
what is shown in circuits 1 to 9. However, the use of a different
C
Capacitor type will generate audible noise due to the piezo
electric effect of materials used for their structure (such as X7R
and 5YU capacitors).
A different value capacitor can be used. A larger value C
S
Capacitor (10nF) is recommended to be used for larger EL lamps
and/or larger input voltage range. A smaller value C
Capacitor
can be used as long as the over all efficiency of the circuit is not
decreased. When using a smaller value C
S
Capacitor, the circuit
will need to be reoptimized by using a smaller R
SW-OSC
value.
