11.2.1
The inductor should have a low Equivalent Series Resistance (ESR) to reduce losses and the inductor must be able to
handle the peak currents without saturating.
Table 3 Inductor selection information
11.2.2
For the output capacitor the ESR is critical. The output voltage ripple is determined by the product of the current through
the output capacitor and its ESR. The lower the ESR, the smaller the ripple. However, an ESR less than 80 m could
result in unstable operation.

The Schottky diodes provide a lower voltage drop during the break-before-make time of the internal power FETs. It is
advised to use Schottky diodes with fast recovery times.
