PRODUCTION DATA.

9.2.2.3 Output Filter Selection

The TPS6282x is internally compensated and optimized for a range of output filter component values, which is specified in Table 4. Using these values simplifies the output filter component selection. Checked cells represent combinations that are proven for stability by simulation and lab test. Further combinations are possible, but should be checked for each individual application.

Table 4. Recommended LC Output Filter Combinations⁽¹⁾

	10 µF	22 µF	47 µF	100 µF
0.33 µH
0.47 µH	√	√ ⁽²⁾	√	√⁽³⁾

(1) The values in the table are the nominal values of inductors and ceramic capacitors. The effective capacitance can vary depending on package size, voltage rating and dielectric material (typical variations are from +20% to -50%).

(2) This combination is recommended as the standard value for most of all applications.

(3) C_ff is recommended for large C_OUT values.
