Hi
进芯片主页,见右边的软件webench,输入参数,点击开始设计即可得到电路图,以及相关参数。

您好:
1、启动需要大于1.55V。但是datasheet上明明写的是MAX是1.55V。如何理解?
2、对于datasheet上page35提到的:
Under Voltage Lock Out Set Point
The Under Voltage Lock Out (UVLO) can be adjusted using an external voltage divider on the EN pin of the
TPS54060. The UVLO has two thresholds, one for power up when the input voltage is rising and one for power
down or brown outs when the input voltage is falling. For the example design, the supply should turn on and start
switching once the input voltage increases above 8.9V (enabled). After the regulator starts switching, it should
continue to do so until the input voltage falls below 7.9V (UVLO stop).
是否可以这样理解,在EN两端加电阻后,高于8.9V启动,低于7.9V停止工作的功能才会有?
而当EN浮空的条件下,上面的功能是没有的?
