IZ3361

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. FEATURES: Fast average current control Programmable constant off-time switching Linear dimming input PWM dimming input Output short circuit protection Ambient operating temperature -40oC to +125oC Pin-compatible with the IL9910 IC APPLICATIONS: DC/DC or AC/DC LED driver applications LED backlight driver for LCD displays General purpose constant current source LED signage and displays Architectural and decorative LED lighting LED street lighting Block diagram: General view of ICs: IL3361D (plastic SO-8 case) IL3361DH (plastic SO-16 case) IZ3361 (dice) Typical application circuit: 1 Ver.00/20.03.2012 IL3361e_tsp 338944 IL3361D/ IL3361DH/ IZ3361 IL3361D pin numbers displayed without brackets, brackets contain pin numbers for IL3361DH.
