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 f
