AS1310 − Application Information
Component Selection
Only four components are required to complete the design of
the step-up converter. The low peak currents of the AS1310
allow the use of low value, low profile inductors and tiny
external ceramic capacitors.
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 6.8μH inductor with a >500mA current rating and
<500m
Ω DCR is recommended.
