We wish to change the inductor and output capacitance values, which takes us off of the recommended values in Table 2 on page 12 of the datasheet. There is not much guidance on the limits of doing this, since the paragraph above the table refers to a high-frequency zero which is not quantified. We need to know if our specific values are going to result in a stable system. Here are the details.
Input: 12 V
Output: 5 V (USB charging)
Output capacitance: 150 uF electrolytic (USB requirement) plus 2x 47 uF ceramic plus 1 uF and 10 nF ceramics
Inductor: 5.6 uH (chosen to reduce the ripple current amplitude)
The double pole created by this combination is at 4.3 kHz, as opposed to the target from Table 2 of over 10 kHz.
