TPS61158: Start up delay time and shutdown delay time for PWM mode

Part Number: TPS61158


I have question regarding the parameter on the datasheet. 

TPS61158 datasheet Figure 8 shows the timing diagram for startup and shutdown for the PWM mode, but I can't find the values for the startup delay, FB ramp and shutdown delay on the datasheet for PWM mode. 

Can you help be obtain this parameters?

        For the start up and shut down delays, we do not have specific values at the moment, they are roughly several hundred us. For the FB ramp, there are 32steps to the reference voltage with each step taking 341 μs. Hope this helps. thanks.
