About ADuM5201 start up timing.

Hi all,

I want to use an ADuM5201 in these conditions:

   primary input supply = 3.3V

   secondary output voltage = 3.3V

   self regulated mode

 

I searched in datasheet but did not find the max time the Viso regulated voltage is available since Vdd1 reaches the ULVO.

 

Thanks for your help.

  • Fred: Unfortunately, we do not have a maximum specification for the time it takes for the Viso voltage to become regulated after VDD1 reaches the UVLO voltage limit. This will depend on the Viso output bypass capacitors values and the amount and type of output load in startup.
