TPS25200: Datasheet Figure 18 not tally with equation

Kelvin Tee

Part Number: TPS25200

Hi

My customer is have below questions

By referring to the datasheet, Fig 18 chart is not tally with equation (1)
eg. If Rlimit is 250kohm, the calculated Ilimit 328.6mA while the chart is pointing 450mA . Is it an error or there is another calculation ?
If it is an error, could you share the correct chart.

In section 9.2.2.5 the example, it should depict Figure 17 instead of Figure 18. Was this a typo?

Thanks

Rgds

    Hi Kelvin,

    Thanks for reaching out!

    Equation-1 is correct but the plot shown in Figure 18 is not drawn properly. Please design as per Equation-1. I will get Figure 18 updated in the datasheet.
