Using the Sluv813EVM and as said in datasheet, I varied R10 from the 8.25K and at ~3.3K the 30V leds started flickering. Until this point, there was no reduction in LED current. I was hoping that when the R10 is reduced the On-time would reduce linearly as stated in the datasheet (I only measured the LED output current) and provide a uniform reduction in the LED output current, but it did not appear to be the case. Could you please explain my mistake....many thanks.
