关于TPS43060问题

Hi

      The TPS4306x provides cycle-by-cycle current limit protection that turns off the low-side MOSFET when the inductor current reaches the current limit threshold. The cycle-by-cycle current limit circuitry is reset at the beginning of the next switching cycle.

      芯片是 cycle-by-cycle的限制，也就是输出电压在保护是应该是输出电压因为过流保护而掉下来，然后芯片再启动想升上去，但是然后会过流掉下来，周而复始。

Hi,

过流保护的机制如上贴所说。另外，手册还提到，进入过流保护状态以后，输出电压会与负载有关。

During an overcurrent event, the output voltage begins to droop as a function of the load on the output

电压最终会降到（输入电压减去MOS体二极管电压）。
