About how to delay power output short circuit protection

DC / DC power module

Main functional requirements:

DC input 16-32v;

DC output 27.4v;

Output current 1.5A;

Input and output are isolated and output voltage is stabilized;

There is only one output of DC / DC power module, but the load end of the end user's power supply outputs two, each of which is connected with 1.1a self recovery insurance in series. It is required that in case of short circuit at each load end, the output voltage of DC / DC power module shall not be reduced by more than 5V before the self recovery insurance action.

Please recommend ti's power management chip, or the scheme that can realize this function, thank you!

       TI的芯片保护功能例如短路保护之类,回复重启的过程一般和芯片启动差不多,你可以调整一下软起动看看?

       没有其他的方式来控制保护的delay启动时间。
