... Even the best switch-mode power supply design cannot overcome the problems that can be caused by a poor layout. For the AAT1265 necessary that C1 and C2 be placed as close as possible to the IC with a good low impedance path to the GND pins of the IC also good practice to minimize the length of the trace from the OUT pin to the output inductor ...
