Customer wants to control sequence through EN pin.
For TPS40322, we can pull EN to GND to disable IC, and float to enable, but we cannot pull EN to 3.3V to enable IC, right?

Hello,
I suggest to use a small FET to pull EN pin low to ensure the part stay disabled.
By releasing EN pin, the rail will start up.
Thanks
