Regarding the rise/fall time of I2C. Why there are minimum values ? what is the impact if smaller rise/fall time happen? please advise.

What is the formula unit for I2C fast mode?? for example: if CB=100pF 20+0.1x100p=20.000....1

Hi, Hermes,

Please ignore the SCL data, that is for common I2C master part. What we focus is the SDA relates when TPS65235 output the SDA.

For the forumla, we need to ignore the unit of the CB, and just put the value. for example, 100pF, it should be 20+0.1 x 100 =30.

any unclear, please let me know.
