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 im-
proves accuracy, line and load regulation of the LED current without any need for loop com-
pensation 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
