ucc25701使用问题?

Other Parts Discussed in Thread: UCC25701

在UCC25701的资料上写着Voltage feed forward compensation is operational over a 5:1 input range and provides fast and accurate response to input voltage changes over a 4:1 range.这句话着么理解?

4:1的输入电压范围可以快速准确的响应,那5:1的输入电压范围会怎么样?

我现在要做的电源输入范围要5:1.

VFF、RT脚的范围都是0.8v-3.0v设定范围,也就是4:1.
