9.5 Capacitor Selection
The convertor requires three capacitors. Ceramic X5R or X7R types will minimize ESL and ESR while maintaining capacitance at rated voltage
over temperature. The V IN capacitor should be 22μF. The V OUT capacitor should be between 22μF and 47μF. A larger output capacitor should
be used if lower peak to peak output voltage ripple is desired. A larger output capacitor will also improve load regulation on V OUT . See Table 5
for a list of capacitors for input and output capacitor selection.

9.6 Layout Considerations
Relatively high peak currents of 480mA (max) circulate during normal operation of the AS1310. Long printed circuit tracks can generate
additional ripple and noise that mask correct operation and prove difficult to “de-bug” during production testing. Referring to Figure 1 , the input
loop formed by C1, VIN and GND pins should be minimized. Similarly, the output loop formed by C2, VOUT and GND should also be minimized.
Ideally both loops should connect to GND in a “star” fashion. Finally, it is important to return C REF to the GND pin directly.
