Tolerance range for electrical current data is stated in the respective datasheet.
For the lower current part of the drivers operating windows, the dimming level is limited by an absolute minimum output current of the driver. For the higher current part of the drivers operating windows, the CLO feature is limited by an absolute maximum output current of the driver. Please refer to specific LED driver Design-in guide.
Due to the nature of the manufacturing processes of LED drivers the typical data of technical parameters can only reflect statistical figures and do not necessarily correspond to the actual parameters of each single product which could differ from the typical data. Calculations are made based on sample measurement data. Going below 30% of the driver’s maximum output power could increase the uncertainty at which the efficiency can be calculated. Efficiency calculations are informative and represent no warranty claim.
