TPS92520-Q1: Could you provide the tolerance of V(CSP-CSN) with 4 sigma limit?

TPS92520-Q1: output current accuracy problem.

Hello Team,

I found that a problem about use the TPS92682+TPS92520,TPS92682 is set consant voltage 50V,TPS92520 constant current is set 1.3A,when I change the output voltage from 4~40V，
the output current will occur change too,

Could you explain to me which factor will influence the output current accuracy? 


I found that other user have the same problem too,and you send a E-mail to him,could you share with me?

    Hello John,

    I can take this offline to explain the details of the sources of inaccuracy in the device.  Note, that this is well within the +/-4% tolerance for the full scale current sense voltage.
