Applications Information
Inductor Selection
Calculate the inductor value (L IDEAL ) using the follow-
ing formula:
L IDEAL =
This sets the peak-to-peak inductor current ripple to 1/4
the maximum output current. The oscillator frequency,
f OSC , is 3.25MHz, and the duty cycle, D, is:
V
V IN
Table 12. Recommended Inductors
Given L IDEAL , the peak-to-peak inductor ripple current is
0.25 x I OUT(MAX) . The peak inductor current is 1.125 x
I OUT(MAX) . Make sure that the saturation current of the
inductor exceeds the peak inductor current, and the
rated maximum DC inductor current exceeds the maxi-
mum output current I OUT(MAX) . Inductance values small-
er than L IDEAL can be used to reduce inductor size;
however, if much smaller values are used, peak inductor
current rises and a larger output capacitance may be
required to suppress output ripple. Larger inductance
values than L IDEAL can be used to obtain higher output
current, but typically require a physically larger inductor
size. See Table 12 for recommended inductors.
