Can MP2161A start into a pre-biased rail?

Hello,
Can MP2161A start into a pre-biased rail?
I need a step-down converter from 3.3V to 1.8V. By the time the converter gets enabled (EN=high), the 1.8V rail will be pre-charged already to around 1.3V. (The input voltage 3.3V is present all the time, it is just the EN pin which gets enabled.) Is this allowed?

Thanks,
Jaroslav.

Hi Jaroslav,

Apologies for the delayed response.
What is the 1.3V from? Is it from slow discharge of output when toggling EN?

Best Regards,
Yu
