    Monisha OM,

    After consulting with the internal engineering team, the internal circuit will disable the output switching within a  couple microseconds of the EN falling below the disable threshold (0.45V).

    Please note that as there is no active discharge on this device, the output voltage will be discharged by the external load and through the feedback voltage divider network.  Additionally, as the PG pull down is asserted when EN = Low,  if you have a resistor between PG and Vo, the output voltage can be  discharge through this path as well.

    Thank you,
