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
