... Detailed Description The AOZ1312 is a member of Alpha and Omega Semiconductor’s single-channel power-distribution switches family. The AOZ1312 is intended for applications where heavy capacitive loads and short-circuits are likely to be encountered. Gate drive is provided by an internal charge pump designed to control the power-switch rise times and fall times to minimize current surges during switching ...

... OUT LIMIT Layout Guidelines Good PCB layout is important for improving the thermal and overall performance of the AOZ1312. 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 ...
