TPS2121: Output Slew Rate

JDJ

Part Number: TPS2121

In the datasheet of TPS2121 I found that there there appears to be inconsistency in data between Figure 7.6 and Table 9.1
For instance for 5V with 100nF. SR is 4V/ms~4kV/s from the figure and 0.78kV/s from the table.
Please let me know your feedback.

Hi Jack,

Thanks for pointing this out. I'll take a look and confirm the test conditions of Figure 7.6 and Table 9.1 and update the thread with the findings, and if we will update this information.

Thanks,

Patrick

Hi Patrick, I wanted to follow up on the above. Were you able to confirm the test conditions of figure 7.6 and table 9.1?

Hi Jack,

I have not been able to get to this yet, but I will let you know when I do.

I will likely only have time to test this starting next week. Please let me know if there is special urgency to this issue.

Thanks,

Patrick

Hi Jack,

Thanks for your patience - I received confirmation that Figure 7-6 is an error and Table 9-1 is accurate to the device. The current plan is to update the data sheet with Figure 7-6 removed.

Again, thanks for bringing this to our attention.

Thanks,

Patrick
