PRODUCTION DATA.
RLIM is used to sense the LED current. To accurately measure the LED current, the RLIM _K_1,2 lines should be connected close to the top-side of measurement resistor RLIM, while RLIM_BOT_K_1,2 should be connected close to the bottom-side of RLIM.
The switched LED current is running through RLIM. Therefore, a low-ohmic ground connection for RLIM is strongly advised.
