Hi,
From the datasheet:
min/typ/max
VENXH EN1/2/3 high-level input voltage:-/1.2V/ 1.26V
VENXL EN1/2/3 low-level input voltage: 1.1V/ 1.15V/-
Question1 - Does this information means:
- If I want to enable: set 1.2V to 1.26V max?
- If I want to disable: 1.1V to 1.15V?
What should be the correct voltage level to enable and disable the IC?
Question2 -
I have a +5V input & 3 outputs (Vout1 = 1.0V@3A, Vout2 = 3.3V@2A, Vout3 = 1.5V@2A).
I need the following sequence: 5V input -> 3.3V -> 1.0V -> 1.5V output.
Can I do this:
1) set EN2 to open
2) output of Vout2 (3.3V) connect to EN1.
3) output of Vout1 (1.0V) connect to EN3. (can 1.0V voltage enable this buck3?)
4) output of Vout2 will be 1.5V (last)
Thank you
