Output Capacitor Selection
Selecting the proper output capacitor is based on the
desired output ripple voltage. Ceramic capacitors with low
ESR values will have the lowest output ripple voltage and
are strongly recommended. The output capacitor requires
either an X7R or X5R dielectric.
The output ripple voltage in PWM mode is given by:
VOUT
IL
1
4
fSW
3
COUT
ESR
(eq. 6)
In PFM mode (at light load), the output voltage is
regulated by pulse frequency modulation. The output
voltage ripple is independent of the output capacitor value.
It is set by the threshold of PFM comparator.

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, a fixed
18 pF or higher ceramic capacitor is needed. Choose a
small ceramic capacitor X7R or X5R or COG dielectric.
