LM27952: Current Setting issue

Part Number: LM27952

Hi,

In our design we have used LM27952SD/NOPB LED Driver IC.

As per datasheet, we have used the below attached formula where we have set IDx as 80mA hence RSET=3.16Kohm resistor. But we are getting around 200mA output from the LED Driver .

The given input voltage to Driver is 3.3V,

       LED Forward voltage is 3.2V.

 

Kindly clarify why the Driver IC is giving 200mA output instead of 80mA that we have set?
