Hi
when i enter the torch mode with maxium range(376mA), there shows about 4A current of VIN,then the SW was shorted to GND.
have you met this problem before?
thanks.

Hi
4A以上是够的。将电流调小一点,不至于烧芯片,然后测试一下波形,看是否有异常?
其次输入电压多少? 是否存在热插拔的可能?
一般来说只要电感不饱和,输入没有过压,芯片很难烧的。
Hi
这个时候的电流肯定是大于了功率电感的饱和电流导致芯片烧掉。
只是这个关机电流明显是异常的,请问你提到的torch模式对芯片LM36010的影响是什么?
