TPS56339能否实现可调电压输出?

Other Parts Discussed in Thread: TPS56339

我有个电源设计需求,输入12V,输出1-11V连续可调,输出电流3A。计划使用TPS56339+数字电位器实现,但是在TPS56339的Datasheet中发现了一段描述,7.3.1节,原文如下The TPS56339 uses an Advanced Emulated Current Mode (AECM) control, ……The internal adaptive loop adjustment eliminates the need for external compensation over a wide voltage output range up to 16V. However, dynamic adjustment output voltage is not supported.


请教一下各位:

1、TPS56339的AECM为什么不能实现dynamic adjustment output voltage,原理是什么?

2、如果使用TPS56339,如何设计才能达到使用需求。

3、如果TPS56339不行,有没有其他IC可以满足使用需求。

谢谢!
