请教大家：J750能不能限流？测试时可否用外接电源？

我们现在测试芯片，不能正常进行，因为会超产生的急ns的电流太大。J750保护而自动停机，但是我们的芯片又是需要这么大的短暂电流的，请大家赐教，谢谢！

If you mean the power, I will suggest you can connect two DPS together to double the power, or use a Buck DC to DC IC to supply such a big current. In this situation, unless your IC need more than the max voltage * max current of DPS. You don't need an extra power.
