Choosing Inductors and Capacitors for DC/DC Converters
Therefore, the external L-C filter must be compatible with the internal compensation. For this device, the internal compensation is optimized for an LC corner frequency of 16 kHz, i.e., a 10-μH inductor and 10-μF output capacitor. As a general rule of thumb, the product of L*C should not vary over a wide range when selecting an output filter.
