Output Capacitor Selection
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.
regulated by pulse frequency modulation. The output
voltage ripple is independent of the output capacitor value.
It is set by the threshold of PM comparator.
Selecting the proper output capacitor is based on the
The output ripple voltage in PWM mode is given by:
In PFM mode (at light load), the output voltage is
