Part Number: TPS2553

Hi,

Could you tell me about TPS2553 operation in EN=Low condition?
Is there a possibility that the output voltage appears at the input of TPS2553 in EN=Low condition?
When voltage exists on the output side,
Customers are concerned about passing through parasitic diodes of internal FET.
