... OUT LIMIT Layout Guidelines Proper PCB layout is important for improving the thermal and overall performance of the AOZ1341. To optimize the switch response time to output short-circuit conditions keep all traces as short as possible to reduce the effect of unwanted parasitic inductance. Place the input and output bypass capacitors as close as possible to the IN and OUT pins ...
