Application Information

The following recommended components are examples selected from requirements of a typical application.

6.1

Capacitor Selection

Ceramic capacitors are used as bypass capacitors at all VDD and output rails. When selecting a capacitor,

especially for types with high capacitance at smallest physical dimension, the DC bias characteristic has to be

taken into account.

Inductor Selection

Inductors should be selected based upon the following parameters:

▪ Rated max. current: usually a coil provides two current limits: The Isat specifies the maximum current at

which the inductance drops by 30% of the nominal value. The Imax is defined by the maximum power

dissipation and is applied to the effective current.

▪ DC resistance: critical for the converter efficiency and should therefore be minimized.

▪ The typical recommended output inductance is 0.22 µH per phase. Use of larger output inductance degrades

the load transient performance of the buck converter.
