10.2.1.2.3 External Component Selection

The external components have to fulfill the needs of the application, but also the stability criteria of the device's control loop. The TPS6213xA-Q1 is optimized to work within a range of external components. The LC output filter's inductance and capacitance must be considered together, creating a double pole, responsible for the corner frequency of the converter (see Output Filter And Loop Stability). Table 3 can be used to simplify the output filter component selection.

(1) The values in the table are nominal values.
(2) This LC combination is the standard value and recommended for most applications.

The TPS6213xA-Q1 can be run with an inductor as low as 1µH. FSW should be set Low in this case. However, for applications running with the low frequency setting (FSW=High) or with low input voltages, 2.2µH is recommended.

More detailed information on further LC combinations can be found in SLVA463.
