Inductor Selection
For best efficiency, choose an inductor with high frequency core
material, such as ferrite, to reduce core losses. The inductor
should have low DCR (DC resistance) to reduce the I²R losses,
and must be able to handle the peak inductor current without
saturating. A 10μH to 22μH inductor with greater than 500mA
current rating and less than 500m
Ω DCR is recommended.
When smaller peak currents are selected, the inductor current
specification can be reduced accordingly.
