Part Number: TPS92200

I use TPS92200D1 to drive LED. But I don’t find the accuracy of TPS92200D1 from datasheet, do you know the accuracy data?

Hi Customer,

You can refer to the FB pin reference voltage from Section 6.5 Electrical Characteristics in the datasheet. The output current accuracy will largely depend on the variation of this parameter.

So this means the accuracy is about 3%,right?

Hi Tim,

Not totally correct. The output current accuracy will also depend on the tolerance of the sense resistor that you use.
