Hi support team,

I am designing a circuit using the PCA9956B LED driver and I would like to know the expected current to flow inside Rext in order to select a correct resistor power rating. 

I am not able to find this information inside the datasheet.

Thank you for your support.

Best regard.

HI 

For the reference in the EVB we select 0402 footprint resistor.
