Dear community,
We have been developing our product with PF3000.
I have a question about  VCC_SD voltage transition time.

The VCC_SD voltage is switched by SD_VSEL logic level.

[Question]
       How long time does it take to switch the VCC_SD voltage range by changing SD_VSEL ?

    Best Regards,
    Koichi Sakagami

Hi Koichi

unfortunately this time is not specified by datasheet, however one

can estimate it using formula : I*t=C*U,

I=100mA, U=3V (SD_VSEL, Vh-Vl),C=2.2uF,

t~60uS

Best regards
