TPS56637: Is TPS56637 damaged if we apply 3.3V to EN when VIN is 0V (no supply)?

Hi Team,

Is TPS56637 damaged if we apply 3.3V to EN when VIN is 0V (no supply)?

I believe TPS56637 isn't damaged because absolute maximum ratings shows 6V for EN.
Is my understanding correct?

Best Regards,

Hi Yaita,

Correct, it's safe with 3.3V EN.
