Other Parts Discussed in Thread: TPS2505

Hi,

I found the below description in tps2505 datasheet. Does it mean I have to enable the boost first before enable the LDO? I need to enable the boost and LDO independently. How can I do?

          Thanks.

     I need to enable the boost and LDO independently. How can I do? EN is a global disable (EN < 0.7V) for the LDO, USB1, and USB2. When EN > 1V, then ENLDO, ENUSB1, and ENUSB2 are used to independently enable/disable the LDO, USB1, and USB2 respectively.
