SLVSB70 – OCTOBER 2013
APPLICATION INFORMATION
Output Filter Design
The inductor and the output capacitor together provide a low-pass filter. To simplify the selection process,
Table 1 outlines possible inductor and capacitor value combinations for most applications.

Inductor tolerance and current de-rating is anticipated. The effective inductance can vary by +20% and
-30%.
(2)
Capacitance tolerance and bias voltage de-rating is anticipated. The effective capacitance can vary by
20% and -50%.
(3)
Typical application configuration. Other '+' mark indicates recommended filter combinations.
Inductor Selection
The main parameter for the inductor selection is the inductor value and then the saturation current of the
inductor. To calculate the maximum inductor current under static load conditions, Equation 3 is given.
(3)
Where:
IOUT,MAX = Maximum output current
ΔIL = Inductor current ripple
fSW = Switching frequency
L = Inductor value
It is recommended to choose the saturation current for the inductor 20% to 30% higher than the IL,MAX, out of
Equation 3. A higher inductor value is also useful to lower ripple current but increases the transient response
time as well. The following inductors are recommended to be used in designs.

Capacitor Selection
The input capacitor is the low impedance energy source for the converters which helps to provide stable
operation. A low ESR multilayer ceramic capacitor is recommended for best filtering and should be placed
between VIN and GND as close as possible to those pins. For most applications 10
μF is sufficient, though a
larger value reduces input current ripple.
