APPLICATION INFORMATION
inductor selection (continued)
In order to avoid saturation of the inductor, the inductor should be rated at least for the maximum output current
plus the inductor ripple current which is calculated as:
DI
L + VO
1–
V
O
V
I
L
I
L(max) + IO(max) )
DI
L
2
Where:
= Switching frequency (750 kHz typical)
L = Inductor value
IL = Peak-to-peak inductor ripple current
IL(max) = Maximum inductor current
The highest inductor current occurs at maximum VI.
A more conservative approach is to select the inductor current rating just for the maximum switch current of the
TPS6200x which is 1.6 A with ILIM = VIN and 900 mA with ILIM = GND. See table 1 for recommended inductors.

output capacitor selection
For best performance, a low ESR output capacitor is needed. At output voltages greater than 1.8 V, ceramic
output capacitors can be used to show the best performance. Output voltages below 1.8 V require a larger
output capacitor and ESR value to improve the performance and stability of the converter.

See Table 2 for recommended capacitors.
