APPLICATION INFORMATION
adjustable output voltage version
When the adjustable output voltage version (TPS62000DGS) is used, the output voltage is set by the external
resistor divider (see Figure 15).
The output voltage is calculated as:
V
O +
0.45 V
1
) R1
R2
With R1 + R2
≤ 1 M
R1 + R2 should not be greater than 1 M
because of stability reasons.
For stability reasons, a small bypass capacitor (Cff) is required in parallel to the upper feedback resistor, refer
to Figure 15. The bypass capacitor value can be calculated as:
C
(ff) +

π x 30000 x R1
for Co t 47 F
C
(ff) +

π x 5000 x R1
for Co ≥ 47 F
R1 is the upper resistor of the voltage divider. For C(ff), choose a value which comes closest to the computed
result.

inductor selection
A 10
H minimum output inductor is used with the TPS6200x. Values larger than 22 H or smaller than 10 H
may cause stability problems because of the internal compensation of the regulator.
For output voltages greater than 1.8 V, a 22
H inductance might be used in order to improve the efficiency of
the converter.
After choosing the inductor value of typically 10
H, two additional inductor parameters should be considered:
first the current rating of the inductor and second the dc resistance.
The dc resistance of the inductance influences directly the efficiency of the converter. Therefore, an inductor
with lowest dc resistance should be selected for highest efficiency.
