Tapan,
I cannot assist in debugging this issue without seeing the signals.
The TPS2557-Q1 does not provide a discharge when disabled, so the long discharge time is likely caused be the load of a out on the output.

Chuck
Part Number: LM25088-Q1 Other Parts Discussed in Thread: LM25088 I would like to know the function of Rramp resistor in the below configuration. Datasheet recommends Rramp ony for VOUT>5V but my VOUT is 5V. And also why a 1M ohm resistor is used.
Webench…
Part Number: LM25088-Q1 Dear Sir,
my customer is using LM25088MH-1 for inverting as below spec.
Vin: 12V
Vout: -2.5V
Iout: -2.5A
sometimes it happened broken MOSFET(Q2) and Bead(FB485,FB486) on testing.
could you help check attached schematic?
