IL3361D/ IL3361DH/ IZ3361
LED Driver with Average-Mode Constant Current Control (functional analog HV9961 Supertex Inc.)
The IL3361 is an average current, mode control LED driver IC operating in a constant off-time mode. This control IC does not produce a peak-to-average error, and therefore greatly improves accuracy, line and load regulation of the LED current without any need for loop compensation or high-side current sensing. The output LED current accuracy is ±3%. The IL3361 can be powered from an 8.0 - 450 VDC supply. The output current can be programmed by an internal 272 mV reference, or controlled externally through a 0 - 1.5 V dimming input.
