参考设计文档设计的4A充电电流,但在正常充电时电流确达到了5A多。请问下是为什么?
采用10毫欧采样电阻,6.8UH电感;

您好,Can you double check the VFB resistor values and the RSNS value? To get a charge current of 5A the sense value would have to be 8 mOhm which would be a significant change. What happens if they remove Q4? What is the experimental charge voltage then?
