powerup simulation

Hi,
I want to do the powerup analysis for my simulation. What value I should select for the rammpup time of power supply?

Can anyone help me?

Thanks in advance
John
 

You should try different ramp up time, i.e. 10us, 1ms, 100ms

Thanks for the reply!

I would like also to know what is the max typ, min rampup time for powerup in normal?

Thanks
 

In some ATX power system, the power up time is in ms level , but in portable system or bettery power,the power up time maybe faster.

you can check your application circuit. and decide the simulation condition.
