I am very happy you can spend your time on my question ,thank U .
I want to know what is the " gain" of the power stage described in Tps54531's datasheet ,as below:
I searched many webs ,but did not find my answer ,and can not think through .

感觉很难描述清楚,因为我们天天看到这个“增益”, 但是却没有详细清楚的描述这个(感觉就像意会难以言传)。
建议你找一些电源的书籍看看或者能明白,例如《精通开关电源设计》之类。

和研发没有关系,这个应该是比较基础的内容,但是又很难描述,所以建议你找一些电源书籍看看(这个内容一般都是有的)

你可以在中文E2E, 或者英文E2E上搜索“gain”的定义,看有没有有用的信息。
我明天会给你一个定义gain的图片。开关电源的书我们这边有,每本对于环路补偿都会有大篇幅的描述,其中应该有”gain"的定义
说这一块基础,并不是说它简单,相反很复杂,之前的大部分芯片大部分都是要用补偿电路的,所以都会有这一块的描述。

反馈会存在一个传递函数,传递函数的幅值就定义为增益。
