AIC1553
The selection of output capacitor dominates the
ESR of the capacitor. The capacitance is
adequate for filtering and the low ESR value
shows a low ripple voltage.
The output ripple voltage can be calculated as:
∆VO
≅
∆IL

ESR
Ceramic capacitor with low ESR value provides
the low output ripple. For required, the ceramic
capacitor parallel a tantalum capacitor is satisfied.
Layout Considerations
Due to the high switching frequency and large
transient current, the layout is recommended to
have a ground plane and short connections to
each component. Minimize the length and the
sufficient traces for power- flow loop. Fig. 13 is
recommended placement for components.
