Hi,
we are using LMZ31710 to generate 1.2V and 3.3V. As we have to maintain the power sequencing between 1.2V (fisrt volatge) & 3.3v (2nd volatge) , we planned to connect the power good pin of 1.2V reguator to INH pin of the 3.3V regulator (as per datasheet page #24 sequencing reference circuit).In both the cases we left SS pin as floating, so that internal soft start delay is 1.2ms.
after 1.2ms 1st regulator vout becomes 1.2V, then what was the power good assertion time (once the vout becomes regulated )
i want to know the power good assertion time once its achieve the required output voltage.
it means time duration between regulated output voltage and power good pin pul ldown release time.
Thanks & regards,
Divya
