The HV9861A is a Buck LED current regulator which claims to be able to maintain a constant LED current in spite of varying LED load voltages, even though it only uses low side current sensing.
Figure 1 , page 5 of the datasheet shows the great LED current regulation over varying LED load voltages. Do you know what the variation of LED current would be like as the input voltage varied?....the datasheet does not say....
