9.2.2.2 Output Filter Design (Inductor and Output Capacitor)

The internal compensation network of TPS6206x is optimized for a LC output filter with a corner frequency of:

Equation 5. GUID-8C6A2EED-502C-48E3-8ACE-7D74509A3590-low.gif

The device operates with nominal inductors of 1 µH to 1.2 µH and with 10 µF to 22 µF small X5R and X7R ceramic capacitors. Refer to the lists of inductors and capacitors. The device is optimized for a 1-µH inductor and 10-µF output capacitor.
