8.4.3 Output Filter Design

The inductor and output capacitor together provide a low-pass filter. The following tables show possible output capacitor and inductor pair values per output voltage. Checked cells represent combinations that are proven for stability by simulation and lab test. Two plus signs (++) mean this combination of capacitor and inductor values works very stable for the listed VOUT range and can be used without change in the target application. One plus sign (+) means this combination of capacitor and inductor values works stable on the reference board (TPS62A0569x Evaluation Module) but can require adaptation to the target application. Check this capacitor and inductor combination more thoroughly in combination with the application and provide layout or BOM options by adding an unpopulated spare COUT location. Other combinations can also be suitable for specific target applications and can be used once validated for stability including measuring a Bode plot.

(1) Inductor tolerance and current de-rating comparable to the device families in the BOM are included in the recommendation.
(2) Capacitance tolerance and bias voltage de-rating is included in this recommendation based on the device families from the BOM. Capacitors from different manufacturers or with different form factor can have more derating. Then larger values need to be considered.
(3) Very stable operating condition with strong transient resilience. Voltage drop with large transients is minimized. One '+' is shown here because gain bandwidth is reduced with this setting so time required for VOUT to return to target after large transients is extended.
