Output Capacitor Selection
Selecting the proper output capacitor is based on the
desired output ripple voltage. Ceramic capacitors with low

are strongly recommended. The output capacitor requires
either an X7R or X5R dielectric.
The output ripple voltage in PWM mode is given by:

In PFM mode (at light load), the output voltage is
Feed-Forward Capacitor Selection
The feed-forward capacitor sets the feedback loop
response and is critical to obtain good loop stability.
Given that the compensation is internally fixed, an 18 pF
or higher ceramic capacitor is needed. Choose a small
ceramic capacitor X7R or X5R or COG dielectric.

voltage ripple is independent of the output capacitor value.
It is set by the threshold of PFM comparator.
