AS1313 − Detailed Description

External Component Selection

Inductors

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 6.8μH inductor with at least 500mA current rating

and DCR of 500mΩ (max) is recommended.
