TPS25980: Unit for some parameter's on datasheet and Cdvdt's maximum value

Kazuki Kuramochi

Part Number: TPS25980

Hello expert,

I have questions for TPS25980's datasheet.
I'd like to confirm about following formula's unit to estimate maximum CItimer.
CITIMER < tGHI/53000

Would you tell me CITMER and tGHI's unit?

Also, would you tell me maximum value of Cdvdt?

I'm looking forward to hearing back from you.

Best regards,

Hi Kazuki,

1. unit for CITIMER=F,tghi=seconds

2. Theoretically their is no limit on cdvdt value. Higher cdvdt , slower is the device turn on. But very high dvdt may be in mF range will have high leakage and size which may not be suitable for practical use.
