在某些直流/直流转换器中,芯片上的逐周期限流措施在短路期间可能不足以防止故障发生。一个非同步升压转换器可通过电感器和箝位二极管来提供一条从输入端到短路处的直接通路。当负载存在短路时,不管集成电路中限流保护功能如何,流过负载通路的极大 In some DC / DC converters, on-chip cycle-by-cycle current limit measures may not be sufficient to prevent faults from occurring during short circuits. An asynchronous boost converter provides a direct path through the inductor and clamp diode from the input to the short. When the load is short-circuited, no matter what the current-limiting protection in the integrated circuit is, it flows through the load path
