9.5 Layout Considerations

Relatively high peak currents of 400mA (typ) circulate during normal operation of the AS1312. 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 CREF to the GND pin directly.
