Component Selection
Inductor values between 4.7H and 15H are recom-
mended. In most applications 10H will yield the best
compromise between size and efciency. The inductor
should be a low-loss ferrite design and must be rated for
peak currents of at least 400mA without saturating. Induc-
tors with lower DC resistance will improve efciency. Note
that the inductor value does not have a signicant effect
on ripple current, so while lower values will increase the
operating frequency, they do not reduce output voltage
ripple.
Some recommended inductor examples are Murata
LQH32C and Coilcraft LPO4812, LPO3310, DO3314,
DS1608 and MSS4020.
A ceramic input bypass capacitor should be located as
close as possible to the VIN and GND pins of the IC. A
minimum value of 1F is recommended. If the battery is
more than a few inches away, a bulk tantalum decoupling
cap of at least 10F is recommended on VIN.
The output capacitor should also be a ceramic, located close
to the VOUT and GND pins. A minimum value of 10F is
recommended. Increasing the value of the output capacitor
to 22F will result in lower output ripple. Higher capacitor
values will only offer a small reduction in output ripple,
while reducing light load efciency by causing the peak
inductor current to increase above its minimum value of
150mA. The input and output capacitors should be X5R
or X7R types, not Y5V.
