Hi team,

My customer needs the information of the rise time of VCC.

Is there any requirement for the VCC rise time?

They need this information to set the rise time of DCDC

Hi Ohashi-san,

Thank you for your reply. We do not have a specification for this metric. However, looking at newer devices, such as DP83826, we have spec'ed out 0.5 to 50ms of ramp time for supplies, so customer can start there.

Sincerely,

Gerome
