Hello expert,
In my design the power coil is 47uH,current sample resistor is 0.1R.Input 30~60V,output 3~50V 0.1~1.5A.Tj -40~150C
Could you pls share the output current accuracy and calculation for this device?

Zhiyuan,
We clearly state that at full scale voltage which is controlled by registers, that a +/4% accuracy is ensured.
We actually test each part such that at full scale (1023 setpoint) it is within our tolerance of +/4%. Here is the specifications that references that test.
Keep in mind that this doesn't include the current sense resistor tolerance. You need to include that in your tolerance calculations.
